- v0.4.5 Changelog:

- ══════════════════════════════════════

- # Major Changes/Additions || WARNING: This update modifies significant parts of the game's gender, NPC, and save systems. Old saves may still load, but world data before this version is considered a legacy format and will be auto-migrated where possible. When in doubt, generate a new world.

- ══════════════════════════════════════

- - Added: 6-Gender System (Trans, Non-Binary, Intersex): Character identity options have been fully expanded! You can now choose from Cis Male, Cis Female, Trans Male, Trans Female, Non-Binary, and Intersex when creating your character. Trans, Non-Binary, and Intersex identities also let you independently configure your own anatomy (genitalia) options, while Cis identities remain locked to their standard configurations. An in-game transformation feature is planned for a future update!

- - Added: hasUterus Field: A new field distinguishing vaginal anatomy from uterine capacity. Trans Female characters have a vagina but no uterus, meaning they correctly cannot get pregnant. This propagates through NPC generation, conception logic, and menstruation/cycle processing.

- - Added: Gender Distribution Slider (World Creation): You can now set the gender diversity of your world across all 6 available genders during world creation!

- - Added: Attraction & Romantic Relationship Sliders (World Creation): Control which genders each NPC is romantically attracted to — including an "Any" option. You can also control the initial relationship landscape of your world by distributing eligible NPC pairs across Crush / Dating / Lovers / Engaged / Spouse. The remainder start Single.

- - Added: NPC Romantic Preference System: Every NPC now generates with individual romantic preferences: which genders they're attracted to, their preferred body build, height, age group, hair/eye/skin color, and personality/kink (NSFW) traits. Trait-influenced logic is used to weight these picks (e.g., Athletic NPCs lean toward Athletic builds, Submissive NPCs prefer Dominant partners).

- - Added: NPC Sexual Preference Matrix (NSFW): A full 38-row preference matrix across 9 categories (Climax, Vaginal, Anal, Oral, Penile, Breasts, Feet, Mutual, Talk, Positions, Extra). Each row has a Hate / Dislike / Neutral / Like / Love scale. These preferences now actively influence NPC decisions and action outcomes during sex scenes.

- - Added: Preference Tab in Character Creation: A brand-new tab in character creation lets you configure your character's romantic and sexual preferences before starting the game. Set your gender attraction levels, preferred body types, cosmetic preferences, personality traits, and kink preferences!

- - Added: Look Around System (Replaces "People Nearby"): "People Nearby" is gone. In its place is a much more expanded Look Around dialog with three collapsible sections — People, Furniture, and Items. See exactly who is in the room (with what they're doing!), what furniture is present, the cleanliness state of each piece, who's using it, and what items are sitting on surfaces. "There's a Glass on the Wooden Table." — that kind of detail.

- - Added: NPC Activity Texts in Look Around: NPCs now have visible activity descriptions when you look around. Instead of just seeing a name, you'll see what they're actually up to.

- - Added: Furniture Descriptions in Look Around: Every piece of furniture in the room is described with its cleanliness state (clean/dirty), who's using it, and any items on its surface.

- - Added: Item Descriptions in Look Around: Items placed on furniture are listed in detail. "You can see a Smart TV on the Entertainment Center."

- - Added: In-Passage NPC Activity Sentence (Full Implementation): When NPCs are present, the passage now shows a naturally written activity sentence, like "You see Jane Doe idling nearby and Robert Smith playing on a game console." More than 3 NPCs overflow into an "Also, ...are here." clause. 500+ text line variations keep it from feeling repetitive.

- - Added: Moodlet System (20+ Moodlets): NPCs — and you — can now carry active emotional states that affect how they act. Things like Heartbroken, Giddy, Stressed Out, Anxious, Aroused, Embarrassed, and many more. Each moodlet has a mood bonus, a duration, and specific triggers. Some are always active under conditions (like feeling crowded if you're a Loner), and some fire from events (like getting rejected).

- - Added: NPCs React to Moodlets: Behavior is now shaped by mood. A Heartbroken NPC won't flirt or pursue romance. A Giddy NPC is friendlier and more social. An Anxious NPC sticks to people they already know. A Stressed Out NPC is more likely to be mean. And much more.

- - Added: Moodlets Show in Look Around: Strong moodlets now appear in the NPC's description when you look around. "Standing around, looking embarrassed after being turned down." or "heartbroken over a fresh breakup."

- - Added: Moodlets Affect Texting: NPC text replies now carry tone based on their current mood. Heartbroken NPCs text back flat and short. Giddy ones reply fast with extra energy.

- - Added: Sex Scene Moodlets: How a scene ends now affects your mood afterward — satisfied or frustrated depending on the outcome. The NPC's satisfaction is also tracked quietly and influences their state once the scene ends.

- - Added: Multi-Participant Sex Module (Directive A2): The sex module has been heavily refactored to support multi-participant scenes. State is now tracked per-pair (keyed by actorId:targetId) instead of a global single pair, fixing a range of consistency bugs in group scenes.

- - Tweaked: "Ask for Sex" Moved & Expanded Under Sex Topic: "Ask for Sex" has been separated from the "Ask" topic and moved to the "Sex" topic. It now gives you multiple sub-options with different intents:

- - Ask for Intimacy — Opens the sex module without a hard intent. The NPC will wait for your initiation or move on their own.

- - Ask for Sex — Gives the NPC a P→V, V→V, or P→A intent.

- - Ask for Oral — NPC intent is oral only.

- - Ask for Anal — NPC intent is anal only.

- - Invite for Group — Invite another present NPC (or someone from the household) into the scene.

- - Added: Director Mode (Giver/Receiver Controls): You can now customize who is the giver and who is the receiver in a scene. The + button adds a participant to the Giver or Receiver role; − removes them; swaps your current assignment. Participants assigned to neither role simply sit out your turn.

- - Added: Arousal/Climax Split: Arousal and Climax are now two separate bars. 100 arousal no longer means an instant climax — the climax bar fills at a rate tied to current arousal. Traits and moodlets influence both. Climax caps at 20% without direct genital stimulation (with exceptions for certain traits).

- - Added: Lube System: A new Lube column tracks each participant's lubrication state per orifice (Penis, Vagina, Mouth). Dry states can cause pain during penetration, and lubrication can transfer between orifices (e.g., a wet mouth can lubricate a dry partner).

- - Added: Sex Scene Talk System (Dominant/Gentle/Submissive/Seductive Tones): Talk actions now support Single and Continuous modes, and your tone modifies the effect of what you say. Dominant, Gentle, Seductive, and Submissive tones interact with the NPC's preferences and traits — submissive partners lean into dominant tones, and so on. Talk actions don't need NPC confirmation; even a rejected topic fires, but repetition makes it less effective.

- - Added: Per-Participant Session State (Group Scenes): Encounter Satisfaction Score values — climax flags, peak arousal, action categories, preference scores — are now tracked per NPC ID and survive save/load. This enables per-participant moodlet firing correctly in group scenes.

- - Tweaked: Fertility Traits Overhaul:

- - Removed Impregnator and Impregnation traits (these are now handled by the preference system).

- - Renamed Nympho → Libidinous with an updated title and description.

- - Added: Virile — Significantly higher chance of impregnating a partner.

- - Added: Fertile — Higher chance of conception across fertile and non-fertile windows.

- - Added: Hyperovulation — Releases multiple eggs; high chance of twins or more.

- - Added: Cheat Console Backtick Shortcut: Press (backtick) or (tilde) anywhere in the passage screen to instantly open the cheat console. Won't fire while you're typing in a text field.

- - Added: Expanded tp Command (Cheat Console): Teleportation is now a full multi-form command:

- - tp — Teleport yourself to any lot.

- - tp self — Bring an NPC to your location.

- - tp — Send an NPC to any specific lot.

- - tp all self [filters...] — Batch teleport matching NPCs to your location.

- - tp all [filters...] — Batch teleport matching NPCs to any lot.

- - Filters support gender, age, relationship status, traits, job, and more. Hyphen-tolerant: cis-female and cisfemale both work.

- - Added: lookup-lot Command (Cheat Console): Search for any lot by partial name to find its ID. Returns lot type and street info.

- - Added: give Command (Cheat Console): give self — instantly grants yourself an item. Handles two-hand linked items, held-item placement, and inventory fallback.

- - Added: moodlet Command (Cheat Console): New cheat command with list, add, addall, clear, and effects sub-commands for direct moodlet manipulation.

- - Added: Multi Save-State System (20 Save Slots): You can now have up to 20 named manual save snapshots alongside the always-present autosave slot. Access it from the side menu. Saves support load, rename, and delete, and are written using a crash-safe transaction system (staged .tmp/ writes with atomic rename and backup/rollback recovery).

- - Added: Save Management Dialog: The old "Create Save State" button has been replaced with a full Save Management dialog. View all existing saves, tap one to overwrite it (with confirmation), or create a brand-new named save.

- - Added: Employment Capacity Planner (World Creation): World generation now auto-scales the number of commercial lots to ensure sufficient local job capacity for NPCs and reserved player job openings. Real-time feasibility feedback is shown in the world creation UI.

- - Added: Character Creation Randomizers: Added per-gender randomize buttons to the character creation app bar (Cis M, Cis F, Trans M, Trans F, NB/Intersex, Random All). Individual dice buttons have also been added for hairstyle, clothing, age, color pickers, and preference dropdowns for granular randomization.

- - Added: 500+ Look Around Text Lines: Different variations so looking around doesn't feel like reading the same line twice.

- ══════════════════════════════════════

- # Bug Fixes

- ══════════════════════════════════════

- - Fixed: Gender Canonicalization on Load: Legacy 'Male'/'Female' values in old saves now auto-upgrade to 'Cis Male'/'Cis Female' on load. All sex logic now routes through a unified getGenderCategory() instead of raw string comparisons.

- - Fixed: Anatomy Toggle Visual Bug: Locked anatomy checkboxes (e.g., Trans Female → vagina) now correctly display as checked visually instead of forcing false.

- - Fixed: Conception Formula Correction: loadFactor now correctly clamps to 1.0 instead of doubling conception chance beyond 100%. Final chance is also capped at 0.95, matching the documented design.

- - Fixed: YAML Recovery Robustness: The YAML history recovery handler now correctly catches additional corruption patterns, including values starting with a comma. String quoting logic has been updated to prevent new corruptions from being written.

- - Fixed: Cheat Console Helper Page & Faulty Commands: Cleaned up and fixed inaccurate lines in the help command output, and resolved bugs in the romantic map commands.

- - Fixed: Cross-Lot Fun Seeking: NPCs looking for fun activities could previously get stuck if no valid furniture was available locally. They now correctly traverse to other lots (favoring commercial lots) when local options are exhausted.

- - Fixed: NPC Work Stress & XP Multiplier: Accomplished NPCs now correctly apply the 1.15x XP multiplier; discouraged NPCs correctly apply 0.85x. Previously these moodlet modifiers were not applied correctly on work shifts.

- - Fixed: Baby Age Group Exclusions: Babies are now correctly excluded from romantic, social, and adult-needs routing in the simulation (previously only 'Toddler' was gated; 'Baby' was missing from checks).

- ══════════════════════════════════════

- # Minor Changes/Additions

- ══════════════════════════════════════

- - Tweaked: Commercial Lot Sliders: The single Commercial lot slider in world creation has been split into Fast Foods, Restaurants, and Companies sub-type sliders for more granular world-building control.

- - Tweaked: Hex Color Tag Support: The text passage tag now works with hex color codes in addition to named colors.

- - Tweaked: Trans Male Anatomy Lock: Trans Male characters are now locked to penis-only anatomy in character creation; Trans Female to vagina-only. Reflecting real identity configurations.

- - Tweaked: NPC Preference Terminology: "Preferred" has been renamed to "Attracted" throughout NPC generation for clarity.

- - Tweaked: Simulation Changes

0.4.0 Changelog:

- v0.4.0 Changelog:

- ══════════════════════════════════════

- # Major Changes/Addition || WARNING: This update modifies huge part of game's map structures. During this early development, expect non-persistent world saves as the game’s structure may constantly change during updates. If you find your old saves/world broken, please generate a new world.

- ══════════════════════════════════════

- - Tweaked: Map Direct Travel: As you see, you can directly teleport to any lot via the "Map" in the side menu. Originally, I only allowed this to travel easier when I was debugging. Now, to prevent game-breaking bugs, I will remove this feature. The player can only travel through the map by going outside first and then clicking the "Go to Town" button.

- - Tweaked: Starting Money: Since there is now a proper way to get money, I can finally change the starting money to "18,000."

- - Tweaked: Residential/Apartment Unit Pricing: Adjusted to the new starting money for balance.

- - Added: "Bathroom Interactions & Bladder Stat": You can now take a shower, use the toilet, or groom yourself at any bathroom furniture! A new bladder stat has been wired to the player, which decays 25% faster than hygiene and is displayed via a new bladder meter in the stats panel.

- - Added: NPC Algorithms and Decision-Weighting System: The NPC will now have few options to do: First, check if they have to tend their needs (Status), if not: they will socilize or travel! The NPC will also decide who to talk to or visit to by weighting and scoring candidates. The NPC will search first in their current location. If they fail, they will go to other rooms. A few failed attempts will also lead them to going outside their lot or performing other task!

- - Added: NPC Socializing: NPC to NPC and NPC to PC is now possible! The NPC will choose who they want to talk to based on relationship, traits compatibility, and so on. They will also choose what topic they want to talk to! Of course, the target they want to interct with will still decide whether they want to or not!

- - Added: Interaction and Interruption Notifier: The Player will be notified if an NPC wants to interact with them. That also includes task interuption! If your task is passive (Loitering or Watching TV) The NPC can now interrupt you if you want to socialize with them!

- - Added: Environment Text The [Look around] text in the passage will show the task the NPCs are doing like who they're talking to!

- - Added: "Invite Over" Topic You can now invite NPCs to your house! Also, "Stay Over" is also planned for a full day stay! While NPCs are a guest in the location, they will not leave unless circumstances like going to work!

- - Added: "Accept, Decline, Ignore" when prompted Accept: Gives you +5 relationship unless the topic is (Mean -5); Decline: Gives -5 relationship (-10 Decline) It will also cooldown the NPC for ten minutes if you decline them; Ignore Will do nothing and the NPC may attempt again to interact with you.

- - Added: NPC-Initiated Sex and Business Requests (Arousal-Driven): NPCs can now initiate sex/business topics when eligible. Their decisions now consider NSFW mode, age restrictions, relationship tier, arousal thresholds, and relevant traits.

- - Added: Expanded NPC Request Logic and Openers: NPC-initiated sex/business requests now use weighted category selection, act-specific request pools, and varied opener lines for better variety and context.

- - Added: Sex Module Freeform Control UI: The sex flow now supports a more structured control layer (You/NPC main tabs + Actions/Clothes/Positions/Furnitures sub-tabs), including hand/perform actions and richer in-scene control handling.

- - Added: Consent Mode Controls in Sex Flow: Consent handling now supports Ask vs No Ask, including NPC pending-action prompts and player responses (Accept/Decline for Ask, Continue/Resist for No Ask).

- - Added: Directional Business Contract System: Business now supports both Pay (you pay NPC) and Offer (NPC pays you), with contract payload/state carried into sex mode and enforced during service actions.

- - Added: Dynamic Pay Adjustment Actions: Pay quote UI now uses adjustable action controls (Add 5, dynamic Pay [$amount], Deduct 5) so the amount updates live before confirming.

- - Added: Offer Willingness Ordering Logic: Offer flow now checks NPC willingness first. If they refuse, it ends immediately with refusal response; if willing, the price/contract flow proceeds without a second contradictory decline roll on accept.

- - Added: "Ask to Have Sex" Under Ask Category: “Ask to Have Sex” is now integrated under the Ask interaction flow (instead of separate Sex category routing), with proper gating checks and automatic handoff into SexModule when accepted.

- - Added: Auto-Start Bridge for Ask-to-Sex Acceptance: Successful ask-to-sex requests can now enter SexModule immediately with one-time auto-accept handling, reducing flow friction.

- - Added: Focus-Lock for Active Interaction NPCs: NPCs currently engaged with the player are now lock-protected from simulation movement interruptions until interaction flow is released.

- - Added: Jobs: 30+ possible jobs! From Fast Food Restaurants, Corporates, and Medical Paths! Also, 8 stagnant jobs that have no tiered paths or promotions. These jobs are janitor, security guard, delivery man, and taxi driver.

- - Added: Go to Work: Player can now go to their work! This also features three phases of work: Phase 1 -> Break Time -> Phase 2. You can choose your performance for the two phases while you can choose on what to do on your free time! Your mood is also important for your performance!

- - Added: Phase 1 & Phase 2 Performance UI: Choose how you want to work! Just want to take it easy? Slack off? or work hard so you can get promotion faster?

- - Added: Break Time Options: During your free time, you can select on how do you want to spend it. By socializing, you can build your current relationship with your co-workers or you can meet new co-workers! Or, you can replenish your needs instead. (Traits plays a role whethe
