It has its faults, but you won't find a better labor-of-love mockery of a genre short of an old Mel Brooks film. As the others have said, it is a little rough around the edges...equipment upgrades cost too much in terms of grind time time vs benefit, a couple of the environment puzzle sections drag on a little long, and minion control is best left to a gamepad...but there are worse criticisms to be levied at a game. Tutorial-through-level-design is well done; after a short (and optional) segment to teach the absolute basics, the finer points [such as how to use the environment or various minion types effectively] are taught through gameplay. The whole game is spent with its tongue firmly planted in its cheek; each of the bosses either turn an old trope on its head or exaggerate it to 11; the expansion pack [Raising Hell] takes it even further, allowing players to discover the eternal fate of each of the bosses; let's just say the devil has a sense of humor.
