Pandemonium! is a average adventure game, that doesn't bring any new ideas to the genre. Total letdown.
The bad points is the story and the game just feels like a 25 page book. Take you about an hour or so to complete, or to get to the last boss. The levels do seem a bit long, which is good. The problem here, is that there are only 13 levels altogether (including bosses), and seems like one of those cartoon games (Spongebob, Ed, Edd N Eddy come into mind).
Overal Pandemonium! is a game to rent first or borrow from a friend. If your a die hard adventure fan, then you might be in two minds about this.
