Old school and punishing!
I mentioned the humor is outlandish, and it spreads from the intro cinematics all the way into the game and ending, with the likes of Ghosts'n Goblins, complete with armor too. So, though it's a nice shift from the moody Diablo, it can be irritating when the game gets too hard to appreciate it. Talking about gameplay, other than the brutal combat conditions, the maze-like level design also doesn't give slack. It still is a gentleman's challenge though, without considering the pestering 'undead' enemies, and is actually well-devised given the dated 90's game engine.
However, as a fantasy RPG, character development and gear customization is almost non-existent in the single-player campaign, forming a void for fans of the genre. Even so, Nox is still a gem of a Diablo clone for old-school fans in the pre-Diablo 2 era, and I believe it's a blast for those looking for nostalgia.
