I don't think you did all the assets yourself in such a short time. The camera can't move in time with the character. I didn't understand the goal of the game. The game looks like a test of unusual mechanics. I like the style of the game. I would suggest to reduce the number of curbs. Add hp to the character instead of one life. Add some goals to make the player feel progress, make the game more linear and then the mechanics will kick in.
