left-handed gamers and those with Intel HD Graphics 3000 cards - beware!
there is no way to remap the I key, so you will not be able use IJKL as your movement keys.
if you try to change W to I you get an alert and then the game stops responding to input events (mouse, keystroke) and you have to force quit.
this is the list of immutable characters: C, I, J, M
it also appears that you cannot remap the mouse button keys.
there is something not quite right with the mouse sensitivity - i use a Razor Death Adder gaming mouse and in this game (and only this game) it performs very poorly. i tried with a mid-range logitech mouse and it worked ok.
if you have a Intel HD Graphics 3000 card, i would recommend not trying to play this game. you will be disappointed.
