Thank you for playing! Sorry for replying so late!
An FPS counter would be handy yeah, I'll try to add one in the future.
Unity quality settings are a bit iffy, but the game is more CPU-heavy than GPU-heavy I think so it's usually not the graphics' fault.
I've been trying to fix audio cracklings when I find them, but it's easy to miss.
I'll darken the background, thanks.
I'll add a map toggle in the future.
A rotate-able camera would be neat, but it is kind of a level design issue as well like you said.
A prompt for switching characters would be nice, I'll add one!
No lewds!!
