That's great to hear.
If you don't mind the suggestion; I would make the swimsuit a tagglable option—However, while I have seen custom settings in Ren`py, such as having the voice volume setting removed for games without voices or separate volumes for different voice groups, I'm not familiar with actually making novels with the engine so I don't actually know if that is even something that can be done. But I figured I would suggest it as something to look into if it can be done.
Having them as separate applications is good, too, for those that only want one or the other.
Stay awesome.
