Hi there.

Just in case you look here before you play the game, there's one thing you can do to improve your experience of playing KZ on the keyboard. Remap the controls. It sounds simple, but it didn't occur to me until the very last level, which gave me immense trouble due to the default key(s) for rolling. Put roll on Alt, jump on Space, and use on E.

I liked the game, but I have to say this was really tempered by the terrible control scheme. Is it possible the developer never played a single PC game in his life? Really annoying, but thankfully fixable.
