The mechanics are sort of nice (frisk/bang a model) but the core game loop sucks ass.
The whole genetics thing is complex and buggy and results in 1. grading busywork and 2. ugly models.
The codebase is painful to even look at with the spanglish naming of things, let alone work with for big changes, so massive change is likely unfeasible at this point without a rewrite.
That said, if there was infinite time and will power in the world, I think this game could use some repurposing of the mechanics (frisk+bang) with a revamped core loop that's about something else. Something that keeps you rolling the dice and clicking "next model" - something other than "ugh this model is ugly and/or rude af, next".
Maybe:
1. keep random generation but don't stray too far from a canonical template
2. do auditions "seriously" (take pictures, don't cross lines) at first to build your reputation (but make it just a few pictures, not clicking on random body parts 150 times)
3. later girls will be sluttier because you've built up your rep as an industry gatekeeper and they will do whatever it takes to make it
