Wow, I was impressed with this game! Its a really cool game plus you can put your own music in it once you figure out how. Although, I have a few suggestions. Maybe there could be some things in the background like planets or a galaxy, not something too distracting, but something to add to the visuals. And maybe along with the awesome steering controls, maybe have a way to speed up or slow down by tilting your device forwards or back. Those are just my suggestions, otherwise great game! Its a really visually stunning game.
