The music was a good touch, the style was reminiscent of old school computer games, and I loved how you could increase speed. I think the pieces I felt missing as I played were clear indicators in the environment how to navigate (holes, walls, and ramps weren't super clear). Also, being fixed to the bottom of the screen was maddening when you had to move back down the map. You have no visibility on where you're going. Still a fun idea though.
