Finally I got myself to beat it. I played it as a warrior, maybe I'll try it again as a wizard or conjurer at some point, but not right now.
Overall the game was quite ok. Nothing unforgettable, but easy to digest and mostly quite pleasant to play. Mainly there are two things that irritated me and I would change about the game:
1. Armor and weapons deteriorate and break up too fast and too easily. This was a problem especially for a warrior who has to depend on his equipment, armor and weapons. Either the rate at which the deterioration happens should have been lessened a lot (like 1/4 of the current rate), and/or there should be a skill or equipment that lets you fix your gear yourself, OR the game should have allowed you to visit shops which fix them more often.
I don't know if I missed some trick (teleportation or something), but in many levels, especially towards the end, you simply didn't bump into any villages/stores anymore where you could fix your gear. Even worse, when you did, fixing your gear was oddly very very expensive, so usually I lost all my accumulated money from journeys to merely fixing my stuff, and usually even that wasn't enough. I don't recall ever e.g. buying anything from the stores, simply because I didn't have money due to constant fixing costs.
So how I tried to counter this was that first of all I carried lots of extra weapons and armor with me, just in case. Sure the enemies sometimes also dropped armor or weapons, but quite often they were some very poor gear, like "flimsy swords" or low level armor, so you couldn't really count on it. Many enemy types didn't drop any gear.
The other workaround (which I also used in TES: Arena which had a similar problem) was that I simply didn't wear any armor until I faced some harder enemies or bosses, but kept them in my inventory. That way I could minimize damage caused to them. Usually I just wore some basic pants and shirts (because for some reason they are indestructible, go figure), and some cape which healed me over time so that I didn't have to constantly use health potions.
For weapons the problem wasn't as bad after you found that halberd of Nox or whatever it was, as it was an indestructible weapon. The only problem was that since it didn't cause fire damage, you still needed some Flame Sword(s) or something in case you faced some undead creatures like ghouls/zombies, as it seems they only could be killed with fire. Near the end you also found a few boomerang type of round throwing weapons which also caused fire damage, and they were quite good as for some reason they didn't seem to deteriorate, even though they were not listed as indestructible weapons. Unfortunately I didn't find them until the last world (10th, Land of the Dead).
2. The game is supposed to be an action-RPG a bit like Diablo, and yeah you seem to get some skill points and level up every now and then... but frankly that didn't seem to affect my warrior much, at least after some point. I never felt like "Oh my I've become powerful!" at any point. It was your armor and weapons which seemed to mostly determine how powerful you were, not at which level you are.
And since you apparently can't even decide how your character progresses when it levels up, I kinda stopped paying any attention to "levelling up". It just didn't seem to matter much.
So yeah, it is more like an action-adventure game where you get to suit up your character to make it stronger.
