Good..good, but some programming issues
The game looks beautiful, but its not backed by good flow of game play. it feels exciting but the ceiling falls too quickly the avatar is not moving more ahead to give a good distance, in simple terms I small mess up your done there is no way to recover.
Its a little laggy giving the experience of a runner game very uncomfortable. Just a few twerks and this game will look amazing.
Keep it up you have the grasp just keep molding it.
