The controls don't seem to work for me. AWSD, only up and down work, unless I try to go diagonally, then it just gets "stuck" moving forever. Arrow keys no directions work unless I hold multiple keys down at once, then it also gets stuck moving.
That's weird, the desktop controls are supposed to work regardless of your keyboard layout. Are you able to play with your arrow keys (which are also supported)?
