Well, just about everything. Gameplay, menus, rendering etc.
What does not
The mouse won't go past the edges of the screen. The game is still quite playable, this is just a bit of an annoyance (you have to spin around to your right every now and again to face offscreen to your left, etc.). You get used to it pretty quick.
What was not tested
Nothing. It's a pretty small, simple game.
Once the mouse issue is fixed (see bug list below), the game will earn a platinum
