This is a really good looking/sounding game. I think it has a lot going for it and could really turn into something wonderful. I loved the animations, sound, and artwork. The concept has a lot of promise too.
I think the controls are a little loose and the character felt a little wild to control. The jumps were a little much and the camera needs some work. I couldn't see where I was going for a lot of it and when jumping/falling the camera shows almost nothing of what's ahead so there isn't any time to react. I also thought the spikes in the beginning as the player is learning the controls was unnecessary. You don't want to punish the player for trying to learn the game.
For a game jam submission, this was very well done and I had fun playing it. I think cleaning up something can really turn this into a great game. Good work!
