Really good game, Its art and design choice are really nice, the camera is really good, the physics are awesome, it reminds me of sonic, but in a 3D done right. Congratulations! If you continue developing this or other games i'm sure it will be a success. There are bugs and some design errors, but thats normal, it takes time to get it right. The only thing I think you should work more on is the story and character/player's motivation to do the tasks, but anyways, Its a really cool game!
