Why use a block?
The game itself was pretty good, but the concept is really nothing new. It has a certain amount of playability to it, and I can really see some potential. But it was just like playing super mario, only it was simplified... literally (you actually control a bouncing, jumping piece of block). Perhaps a ball would have been more convincing. Better yet, I can see a ball having to bounce through all those obstacles that you made, but some with sloping terrain so it would slip and therefore provide the game with more challenge. Just a suggestion. It would be interesting to see another improved version of this from you.
