You guys did a really good job! The only critique I found is I have to jump with Z. Y and Z are switched on german keyboards so it's really hard to have fingers on X and Z for me.
Dang, sorry about that! I should start making the controls be either Arrow Keys+ZX keys or WASD+JK keys, or even Arrow keys+XC keys: it seems that should fix things up. Thanks a lot for pointing it out!
