Fairly entertaining
This seems like it had more effort put into it than the average game. I still did not like it as much as I could because there was not that much detail put into it. The positive sides are that the graphics are good and work in their simplicity. I also thought it was funny when a character fell on the halfpipe and fell off the screen. Yeah, that was supposed to be something to avoid, but still funny to watch. It does not have that much of a point but most games here don't anyway.
It's fun to just see the little animal fly around. You actually are avoid to find a surprising amount of tricks you can pull with the controls you are given. It is still probably better to throw in some more stuff. A suggestion would be to make the character move in the middle of the screen. It would not look as graceful when he lands, but would give you more freedom.
