Congrats!
+ I love the idea. It is simple but the mechanic has a lot of potential.
+ Great art style (love the eye of the player and how it reacts when you jump!). Great and simple background.
+ Audio is simple but more than enough for the game.
+ The levels are well designed.
- I think the movements of the player are difficult to control is hard to make the player move the way you want.
- I prefer being able to replay a level more rapidly but I don't know how to do it in your game as you have to animate even the camera movements.
- I would have added some extra easy levels before the hard ones
