It isn't working on my linux machine! D:
It starts up and displays the title screen, but none of the keys do anything. What's going on?
Aaa I'm not sure! It works for others, however there's one thing that could cause that.
If the game detects a controller connected to your computer at all, it'll prioritise that, and ignore the keyboard! Make sure you don't have any controllers plugged in, and disable any joystick device drivers like vJoy.
Apparently, it was detecting my mouse as a joypad, so I unplugged that and it worked fine! It's pretty inconvenient to have to unplug my mouse every time I want to play, though.
Still, really fun game!
