I want to find out if a mouse can be used with the game.  I cannot use a keyboard and it would be too hard to play if I can't use the mouse.  I really want to play it.

Hey- yeah, the game can be played completely with the mouse (except the escape key to access the game menu).   The game is set up such that the right mouse button moves forward when held down. (This is in addition to WASD and arrow controls.)  

thanks.  Glad to hear that
