I like the simplistic art style. The spell or item for number 1 didn't seem to do anything to the enemies though. The music worked well for the game :-)
Are talking about the little bugs? If you are you can only kill them when you get spell 2 by killing the blue slime thing. I wish I would of just done a level system, in a way I guess it is, but it's more confusing than it needed to be. I wish I would of seen this post earlier.
