Arrow keys to move Z to jump X to shoot Press Z in midair to boost in four directions Move the cursor to determine the engine XY coordinates of that spot. Use the booster to slip and slide around those slopes. Fun. You cannot rotate or scale the screen while playing, but the engine is capable of platforming that's rotated or scaled. Just not on the fly.

This makes sidescrolling, size, and rotation of the screen elements much easier. Also, like, SLOPES WORK! Going up AND down them! Finally!
