Good game so far, though I haven't seen much that I hadn't seen before yet. I'll probably comment more at a later time.
I'm unable to run setup.bat (I wonder why?) and I was wondering why you didn't include a default setup file , as the game looks utterly atrocious in 320x200. In fact, I seem to remember there was no setup file in the original demo, but I could be wrong as it's been a long time.
Anyway, if anyone else is having trouble in this area, this is the acsetup.cfg file I stole from another, more newer Windows friendly game. Keep in mind save files are incompatible across different resolutions. Apologies if I messed up somewhere, somehow...
