I would play this game with my brother a ton when it came out. It is so ridiculously hard and unfair, but we found a way to make one of the characters invincible through a glitch, and that allowed us to progress to the 2nd to last stage.

The game would softlock if you performed this glitch, and we just weren't good enough to make it to the end without using it, so that's as far as we had ever seen. A terrible, yet somehow addicting game.

I may actually try to beat this game some day, if I'm really looking to punish myself!
