Hello, bought that game recently and the default controls are something between awful and strange. The attack and block is mapped to the mousebuttons, but moving is mapped to the arrow buttons. The game is old, i know, but hell...
Well, tried to remap the buttons for movement to WASD, but somehow the game wont let me change the mapping for move up and down. i also tried to find a config file for the keyboard mapping or a config file in genreral, but found nothing so far.
Therefore my question: Is there any way to remap the button layout in general or a way for controller support?

Hi! I just started playing, and I had the same problems. I changed it to wasd, but the game did not show it in the settings. Still it worked.

Try playing, maybe it works for you too?
