I just uploaded the Linux version of the game. I was only able to test it on Windows with VirtualBox and Linux Mint (the game works but the movement is rather irregular) and on my brother's Raspberry (here too the game works with a small lag every now and then). Let me know if that's OK with you.
Hey sorry for the late reply. As far as I can tell it works perfectly with a keyboard, but the controller tends to be a bit unresponsive when trying to turn.
