Have a check at our trailer!
We were originally intending to go with a flat purchase price, but we ended up going with pay what you want because we decided we'd rather put this bit-sized experience in the hands of more people than have people turned off by a purchase price.
We offer a Windows, OSX, and Linux build of the game. Windows does have the most support on the dev end so please tell us if you run into any issues with any of the builds!
Hope you guys have fun blasting lasers and flying through space!
