The first level where you only have on white circle seemed to be impossible. The square never moves, hits you back for as much as you hit it for every time, and has more health...
Yeah, I noticed that a few minutes after the deadline -- it was a mistake from a "fix" a few minutes before the deadline. I fixed that after an okay from a #ludumdare op.
That was fun! Although I'm not sure if I reached the end or my game got stuck midway through it. Good job! I like the simplified strategy game approach :D
Was okay till then!
