Formamorph [v1.1.8] [FieryLion]
An advanced, AI-powered text RPG engine with extensive 3D character customization, you can create your ideal avatar and watch as your body changes and evolves throughout your adventures. From hairstyle and eye color to starting body shape (hourglass, pear, apple), the customization is in your hands.
The engine focuses on the bodily transformative aspects of adventure. You can experience changes such as the size of your belly/breasts or the overall fat distribution in your body. You can undergo virtual pregnancy, breast/belly inflation, weight gain, and more. With AI-powered storytelling, each playthrough is unique and tailored to your choices.

v1.1.6-1.1.8
Dynamic Stat Logic: You can now write Javascript code to update a stat based on other stats! FULL GUIDE HERE
AI Notes
- There is now a Notes panel in the left sidebar
- Notes will persist for the entire game and get saved/loaded with the game saves
- In the future, the AI might be able to update the notes, but not for now as that requires much more testing
Revamped Save Format
- Resolved the exponentially growing save file issue
- Old save format will be automatically converted when you load it with the new version
v1.1.5 Hot Fixes
– Fixed major bug where repeated edits of a world will fail to save
– Added abort button to stop generation early
– Added the ability to disable the choice generation and stat updates in settings(this speeds up by up to 3x because the game doesn’t update choices or stats)
– Added the ability to delete stat updates in the traits editor
v1.1.4
Storing and Editing Worlds
You can now edit and upload your own worlds into the game, the edited/uploaded worlds will be stored and persist across page reloads!
- However, you should still down load backups of your worlds as your browser data could be reset.
Source Code Released
Bug Fixes and Improvements:
- 3D model parameters (belly size, breast size, fatness) can now exceed 100%, previously the 3D viewer used the 100% percentage which meant you could never exceed 100%, even if maximum belly size got increased to 1000.
- In-game Location tab description showing the AI prompt instead of in-game description of the location
- Removed file size limit of 5MB when uploading music or images in world editor
- Load menu: move download save button to front, move upload save button outside scroll. Previously small phones couldn’t download save files
v1.1.0 – v1.1.3
- Added quality TTS (only available on Chrome and Edge)
- Added language selection
- Improved responsiveness by 20x times! You now see narration text nearly instantly rather than waiting up to minutes for the AI to finish writing the entire response.
- Removed the complicated JSON formatting, the AI can now respond in a much simpler format, this should greatly increase the success rate of parsing AI responses and allow you to use even regular role play AI models!
- AI can now see player traits information and more accurate stats data (including current and max stat values along with stat descriptors)
- Note that the AI still cannot give you or remove traits
- The Stats panel now show +5 or -2 in front of the stat names to indicate change
- Added default setting to limit AI event to only one paragraph (this prevent AI from writing too much and going off-road, eating up precious memory tokens)
- Added the ability to edit the AI responses and player stats
- AI can modify the maximum value of stats
- Fixed bugs:
- Entities list now work
- 3D character viewer often didn’t load the customization data
v1.0.3 Patch:
- World Editor:
- Added option to toggle the 3D character model or not for that world
- Fixed major bug: Stat editor doesn’t show a stat min, max, or regen values
- Added 2 new worlds: Valentine Survival and Reincarnated as a Drone
v1.0.2 Patch:
- Error messages are now way more informative on what went wrong
- Revamped the entire save load system to use IndexDB to avoid the 5mb localstorage limit
- You can now download and upload save files
- Reset AI settings now also reset the system prompt
- Fixed bugs
- Game text showing nn instead of newlines
- Traits applied max stats incorrectly

All the complaints below about the game not working is because the initial version was uploaded to this F95 thread too early and that version wasn’t playable Q.Q. It since has been fixed
You can freely modify the world and share it, I hope maybe I can create a space for sharing and playing different worlds.
For the AI Settings you can freely set the AI endpoint yourself, run it locally too. By default it uses a small AI model (nemo gptq) hosted on my potato PC.
NOTE: by default the game use very slow AI on my potato PC. Please follow my guide below to setup freeee AI model that’s 10 times smarter and 100 times more memory on
Those with Local AI: you need to use download version because browser security blocks access to localhost ports.
