Oh yeah, I'm pretty aware of the funny hitboxes with the chatroom quickmenu... After the jam is over, I'll probably try to fix that with a small update.
Also, there is a way to play all of the routes in one day! A lot of people have completed the game once they found out how. It won't affect your progress or the game itself negatively.
Otherwise, I'm glad you like the artwork and characters! I put a lot of effort into developing them...
