The idea of the game is quite nice. I like the nudism aspect. I've read the update plans and the other suggestion comments, so I know you're aware of the desires for a map, and for less frequent unavoidable encounters. I'm sure you've got plenty of suggestions for different creatures too (though I wouldn't mind more bug-type ones.) Rebinding the controls will also be a huge help, since it looks like it's just the "reset to default" in that menu.
One thing I want to say is: I have an injured hand, and the rhythm part is very difficult for me as I can't press instantly. The visual indicators are difficult to follow because they happen instantly, and once the rhythm becomes unpredictable with multiple enemies, it's a little bit impossible for me to react with my motor skills. It seems like the rhythm is pretty much required for surviving encounters a lot of the time, though. Combined with the current frequent encounters, the sex minigame starts to become more of a nuisance than a fun "combat" mechanic.
Would it be possible to add a sound cue as an accessibility option? It's much easier to register a sound rhythm than visual. And/or, there could be a way to see the press timing coming up, like a rhythm game, instead of the button and the pink ring being instant. (Does that make sense? I think I explained that alright.) These are what allow me to play rhythm games.
Finally, the lighting at night can make it very difficult to see tentacles and stuff, making unavoidable encounters less enjoyable. Either making it less dark, or maybe having a more visible outline would work?
Either way, I'd like to play demo 2! With a bit more polish, I'd certainly support a game like this.
