The game is a bit awkward to play because the arrow keys aren't available for movement. I'm lefthanded, you see, and my mouse is on the left side of my computer. I don't have the muscle memory for WASD, and trying to cross-over to use them with my right hand feels awkward. Not a complete dealbreaker, but if there's anything in the game I have to move and shoot fast, I won't be able to do it, because my left hand is doing everything.
