Nice dancing monster!
I have a few nitpicks here and there but the character and the sprites look awesome!
- The main menu font is a bit hard to read because it blends a bit with the background
- The music is not looping
- The movement is a bit too fast for the camera to keep up with it very well. I would suggest either slowing them down or making so that you would see more of the level at one time
That's about it! Very solid prototype. :)
