The gamespot review misses the mark: its a platformer with inventive 3D graphics and level-design.

User Rating: 7.9 | Pandemonium! (Platinum) PS
I recently got this out of my bookcase and I had forgotten how great a platfomer this is. The later levels are creatively bizarre and there's a strange off-kilter sense of humor to everything that keeps this from being "just another platformer." Its not perfect though -- the game is hard and you have to die several deaths in a level before you figure out the best way to get to the end of the level without dying. Sure lots of platformers play like that but sometimes the enemies cant be seen and you cant avoid getting hit by them. Still a great game from its time and deserving a better score than a 5.4
