it's a fun and simple little game, the only thing that would raise my rating up to 5 stars is if the dev changes the "jump" to happen when you press your finger onto the screen, rather than when you take your finger off. right now it feels like you jump way too late or you can't get the timing right, but that's because they have the jump action programmed to happen upon release of the screen. that is my only complaint, everything else is pretty smooth and nice.
