Squirrelfall thrusts the player into the role of a squirrel struggling to survive as he falls to certain death. A squirrel knows that just because you die in the end, doesn't mean you can't have fun on the way down.
Move the squirrel with the mouse to avoid obstacles. Rotate the squirrel with Z and X. Space uses a special move, which has a meter that runs out while in use. The special moves depend on the rotation of your squirrel.
