I got to 3200 score before I stopped playing because there didn't seem to be anything else to do. I think it would benefit from a time limit, or maybe the player should get a game over if they touch the floor, that way they would have to try and keep the player object always on the platform. It would add a layer of skill and give players a reason to try play again and try to set a higher score. I think something as simple as making the floor lava would add a lot to this game
