Outwit gravity, race the clock, explore new worlds, and pay what you want!

I've set a minimum price since you do get a Steam key with your purchase and I need to discourage key re-sellers. You can still grab the free demo if you're flat broke.

I've set a goal for the sale of $250. I've been struggling to save enough money to upgrade to the Oculus Rift DK2, but this would put me over the top. My next VR project would benefit greatly from the positional tracking on the DK2.
