I'm probably gonna be of no use, but I'm gonna go ahead and ask questions anyway.
Have you been playing the demo on RPCEmu? I've done so, and my god, the keyboard controls are complete shit. I don't know if they can be redefined, because I honestly couldn't play the Archimedes demo with such a terrible layout. I could move around okay enough and kill the first baddie, but I couldn't for the sake of my life figure out how to pick up that goddamned sword! It was that bad!
Demo did have a mouse option, but I couldn't figure out how to get that to work. If you did, I really wanna know.
You must have had the patience of a saint to get through the first level, because I gave up on that fucking demo just a few minutes in it!
