I liked this. But it gets quite fast at some point, which is ok if Z, X, C and V are all next to one another but that isn't always the case. On my keyboard layout the Z key is halfway across the keyboard, making it quite difficult.
That's a great point. I originally planned for a slider to control the speed of the level (the code actually works, I just didn't have enough time to put in an UI for it... ). Though rebinding would break the theme in this case.
