While this game does toe the line for me in a lot of ways, and does fall over it not infrequently... That's more of a me-thing than anything else, so whatever.
I have to give credit for a couple things, because damn. First, it seems like the dev has done a great job taking on some of the feedback about gameplay elements that maybe weren't so great. Not the first dev to do so (thank fuck), but certainly not a trait you can find everywhere. Revising your opinion on a thing after dumping a bunch of time and effort into it is not easy, so yeah. All the kudos.
Secondly, the thing that is somehow even rarer than the above. Some actual variety in nipples. Given the genre, I have no idea how this has been so overlooked. But it's such a great way to bring some more variety into the characters, and makes them feel more unique and interesting. Hopefully more devs take note in the future.
