Planetary Drift - Arcade Racing

First 3 maps of a racing game I'm working on. Planetary Drift is a racing combat game. The storyline will focus on gathering energy to hold entropy at bay, and is inspired by classic and indie racers. There will be a campaign with at least 10 maps, upgrades, and an endless mode that finds you racing through procedurally-generated courses. Your highest scores for each map are saved to your machine. 

CONTROLS:

Left/Right = Turn. Turn for over a second to get a speed and handling bonus that lasts the rest of the course. 

Up = Contextual

Down = Contextual

Enter = Pause, start, continue if you're dead.

Touch the left side of the screen to turn left. Touch the right side to turn right. Touch both to brake.
