There are quite a few games like this, but I have to admit that the theme of this one goes extremely well with the Newgrounds website. The concept is simple & clean, there isn't a lot to the game which makes it easy to pick up & play. The only thing I have to say is bad about the game is the way a bird or dog catches you. I've gone hundreds of meters a second, and have been caught in a birds mouth. I would logically think I would rip through the birds stomach out the otherside, but no.
Overall, it's a good fun game worth playing. I've played it quite a bit personally.
