I rated the game high, specially on style (music and graphics are excellent!). However, I didn't have a controller handy and I suffered a bit with the controls: because the character moves relatively to the center of the screen, but the direction is mouse controlled, it is hard to keep it aimed as the player character moves over the screen. I am sure it feels much better with a controller (I know you mention this on the description, but mentioning it because of the Jam rules).
Also I would like to see a fast restart key.
Otherwise, top quality!
