Algodoo

This is a fairly simple tracked tank, albeit with suspension, and powered by my supercharged Ross engine.
Doesn't have any gears to cycle through, but can go in reverse.

Hold Q briefly to go rightward,
And A to go leftward.
Press Z to apply the engine brake.

Press S to toggle the Drive brake,
Press F to toggle the Clutch.

(Starts off with the Drive brake applied).

-Fixed a few performance issues, added in an obstacle course.
