Few comments:
Interesting game. It'll be better if the controls were smoother, so changing the moving speed when creating the game will help.
Better control buttons will be nice. Constantly using the mouse to click restart or next level gets frustrating easily.
Graphics are a little too simple. Maybe have a few different mode concurrently that is like "Oo" (A game that is really messed up, simple graphic but still fun).
Get another sponsor if you can. The mario thing gets on my nerve :/
I hope these comments will help you!
