# Note: to me, the control scheme of this game is *terrible*, totally
# unusable. H J K L for left/down/up/right is OK (vi and all) but the
# diagonals are Y U B N. I suppose since it's a roguelike, that's a
# standard in the roguelike world... It's not configurable in this
# game, meaning I'm never going to enjoy playing it very much :(
