What? Dang. Yet another game incompatible with my Dvorak. Still, I tend to assume that a lot of games in environments like this are from hobbyist devs who are still at the stage of "throw things at the wall and see what sticks." So I'm not too bothered by it; I don't expect full compatibility from this level of game design.
(By contrast, a full-fledged game from a professional studio has no excuse for having hard-coded keyboard controls. See "Sherlock Holmes: The Devil's Daughter", which I was managing to fumble along with until the eavesdropping mechanic required manipulating one cursor with the mouse and the other with the keyboard, simultaneously, as they randomly move away from the target.)
