In either case an 800x600 screen resolution with 16-bit color is required. The software rendering doesn't look that bad and the 3D visuals don't look that great. The dungeon interiors look pretty basic as do monsters and other characters. And I mean basic. Animation is limited and the graphics are passable but hardly state of the art.
Sound effects are equally Spartan.
It sounds like someone was using a little bit too much helium in the sound studio if you know what I mean. The game can be played in several views, all of which are somewhat clumsy. The full screen view map overlay blinked in and out and seeing your character information was problematic. The half screen view was the best overall, but the area at the bottom took up a lot of room in ways that seemed unrequired. Overall the utility of the interface was there, but it wasn't as easy as it should or could have been to use.
