Yeah, I used to watch it when it was on Cartoon Network. It wasn't that great of a show, but the Game Boy Advance game is, well, a deesaster. The trouble is, it's too difficult. You move around in an environment similar to the classic arcade game Marble Madness, trying to collect clones of Dexter's sister, Dee Dee. Only trouble is, there's way too many enemies and the environment is totally way too big with doors and portals and stuff. The map, selected with the select button, doesn't really help at all. I was expecting a 2D side-scroller and what I got was a 3D collectathon. A sucky one, at that. This is made by the same people who made the awful Powerpuff Girls game for the N64 (which was, surprisingly, released AFTER this game was!) Well, anyway, avoid this like the plague.
