Very cute platformer with a nice glide mechanic. Overall the controls felt nice which is very important for a platformer.
I liked the built in tutorial. While going through the tutorial and testing around, I did die a few times and needed to start over. It would be nice to have some waypoints after some key learning spots so that if you die you just go back a little not complete start over.
I think some background music could have really helped set the mood for the game. The sound effects that were available did fit in nicely.
One of the rotating spike traps sent me flying way way up high and took a long time to glide back down. While maybe this can be used to bypass a lot of the level, I'm not sure it was intended.
Art style and character were really nice. Keep at it!
