Great Game
I really enjoy your game a lot. The concept reminds me a lot of Canabalt, but still has it's own unique look and feel to it. The "enemies" that cause the screen to shake can get a little distracting at times, but it adds to the game and makes it more amusing. The only real suggestion I have is Newgrounds medals. I was a little disappointed that achievements were exclusive to another site and that NG medals weren't supported.
