I played the earlier versions of this game and it's actually REALLY impressive how far it's come. I tried making my own RenPy game once but quickly dropped it after realizing what an absolute shitload of work it was. For anyone not familiar with how much it actually is, I'm talking literal hours just to get a few minutes in game (if you want to include AI images that don't look like garbage and clean up some errors that is - and yeah, granted, I did walk into it with zero experience in coding whatsoever). Aside from that it's really nice seeing a game like this not get discontinued and completely abandoned for once.
There isn't really a lot to complain about in this game but one thing that did bother me was that once you get the money for the gym subscription you can grow WAAAAY to fast. If men are much less prone to muscle building in the setting of this game's world it would only make sense that you'd have to work your butt of just to get to a stage that's comparable to the girls innate bodies. I honestly wouldn't mind at all if you needed like three times the experience for muscles and cardio. And maybe it'd even be nice to have some roadblocks in between that gate-keep your growing progress until you complete a certain task or get a certain item or something like that. Tbh I also wouldn't mind if you had to get the steroids for the step sister earlier so that it would take a little longer to get to her higher stages. Ig that's about all.
Also, basically no spelling errors or typos in this game which is pretty nice.
