I like the simplicity of this game, easy to learn, and easy to control. Somehow I don't feel like it is happening in space. After 7-8 points it became a bit repetitive. I think it is not enough, I felt something is missing. Maybe you should move the camera slowly forward to urge the player to jump, and also move the planets. At the launching and the landing the spaceship makes a weird flickering movement. Ads are disappearing after 1-2 seconds.
