If u want somebody from non-english speaking region of the world to not play yr game, then you'd make fix key controls. Sorry, I tried, but it is just not enjoyable to play with present settings ("A , D to move your hero + QWERTYU Hotkeys").

I don't know, maybe I just didn't find in options, maybe it doesn't exist at all, but "Movement: WASD" keys are impossible to change. Not everybody here are with QWERTY keyboards, and if u have any other, this game with current keyboard options is just not playable. I suppose that at least 20-30% people here can't play this game, just because they don't have the keyboard author ment to be.
