This was one great game! The soundtrack keeps you motivated to fight. The level design kind of makes up for the limited number of creatures to fight. This is kind of uneven. Some of the middle levels were harder than the latter. It could have been spaced more evenly. But the experience is gritty. Considering that this was the early 90's, I'm surprised they pulled this off. The quality is astounding for what they had to work with. All the controls are tight. The way the sprite bobs when you walk. The ending was disappointing. It just became a very hard 3D platformer, when they could have just added another character.
