I really don't like this type of rhythm game, or rhythm games in general, so I can't really give great feedback. I'll do my best.
Level 2 was too hard for me.
I thought the dialogue some of the people said was funny when I walked up to them.
Mixing Arrow Keys + E + Mouse for the controls was little rough to work with. Let the player navigate menus using the keyboard so they don't ever have to switch hands like that.
