Release 0.29 2020-03-08 (Public Access)

Yaffaif Build v0.29 is now available to everyone.

Descriptions have changed a lot in this release, adding more detail, as I revised things to be able to handle more species and colour transformations. I also changed the size reporting from BMI to Body Fat Percentage (BFP) as it is a lot more reliable for heights outside normal human ranges.

New stuff:

  • Added the village gate, side street, and guard’s house
  • Added a new character Alexis Ward who guards the gate to the village
  • Alexis can start the incomplete Village Bandits quest
  • You can get beer from the bar in the kobold mine
  • Added Body Fat Percentage (BFP) and use this instead of BMI to describe characters
  • Added descriptions of head and body including fur colouring and patterns
  • Added skunk as a starting species as requested by the first Genetic Engineer patron

User interface stuff:

  • Added a credits tab for the people who have helped support the project
  • Added pre-built characters (there are none so far) to the Patreon build
  • Added a skin colour customisation in the character builder
  • Show colours in some kind of order
  • Fixed a layout issue in the divider between status and controls
  • Fixed the initialisation of the character builder so the initial height and weight are correct

Other bits:

  • When talking to a character questions can have a cool down before they can be asked again
  • Talking to a character can build trust and friendship
  • Added xkcd colours to the list of colours the engine knows about
  • Fixed a bug where the description would only mention one thigh
  • Fixed a bug where sex experience was not being awarded
  • Fixed a null pointer exception in Debug mode

Known bugs:

  • Kobold guards have been caught eating their own “weapons” - it’s emergent behaviour (sort of)
  • If the player dies the game pauses briefly as it runs several in-game hours of “simulation”
  • Starting character sizes may be a little off after changes and need some further tuning

As usual, download from the usual place, and start a new game. Previous saves will not have the new content, and will likely fail to load.

If you would like to support the development you can do so on Patreon where there are a number of different rewards, including walk-thoughs, early access, developer documentation, and more. It would be really appreciated as I have very limited income at the moment. Alternatively, if Patreon isn’t your thing I have a tip jar on ko-fi


Ok, I downloaded it and got it to work with command prompts, but debug doesn’t work, as it can’t find gamefx2.props. I used 7z to extract it and the .bat files just say install Java.

You’ll need to re-install Java to get it to work properly I think.

The file gamefx2.props is one you have to create following the instructions it is not included in the archive. Though you can force it from the command line using the arg --debug at the end of the command.
