no, it's not. Honestly, I haven't tested my game on Linux, I just built it by default. The game is intended to be played with AWSD + arrow keys OR both of the gamepad joystick with normal direction. Sorry for the inconvenience, I'll try to build the patch/fix tonight. Thanks for the info :)
Well, the Linux version runs. Moving with keyboard works. On the gamepad only the left stick works for the white character. As soon as I used the gamepad, keyboard inputs stop working...
