The game has some okay graphics and the loot system is decent. If you enjoy looting corpses for a slightly upgraded item over and over in a noxiously repetitive manner then I say go for it.
Five people in my office bough the game. I played it on very hard and beat it. I was the only person to reach the end despite everyone else playing on normal difficulty.
I beat the game out of spite. I never felt so angry at a game before but my sheer hatred of it drove me to finish.
I guarantee most positive reviews come from people who did not finish the game. It's just not fun after the first 10, 20, 30, 40, infinite floors in the same dungeon.
