This game is fun, and I enjoy the concept and the artwork. The UI fits well with the theme of the game. It would be nice if the character movement speed were increased, as I found it impossible to beat level 3 without reviving simply because I couldn't get my character to move up and down fast enough to get from the top of the screen where one demon spawned to the bottom where the other demon spawned before he could make it all the past me. Everything else feels balanced.
