It's a while away yet, but I'd love to include some of these ideas in the 'More Personalities' update.
My original vision for this game was to use procedural generation to create an endlessly replayable weight gain simulator. Probably too ambitious for what I'm actually capable of making, but that's still my aim.
The next update, 'Jobs & Home', will expand more on the jobs and interests held by the girls, which will hopefully add an extra dimension to them so that one Quirky girl is not the same as the next.
