Cubes? (Future Games)

Cubes battle it out on a birthday gift!?

This game, made in 5 minutes (wow), is a test on how to make a 3D 3rd-person game with only pure javascript. The 3D graphics combine with a 2D environment to create an interesting game. Use the mouse to move the red cube along the gift box. Do not touch the orange cube. If you go onto the vertical side of the gift, you automatically move down. Don't die!
