It's a really crappy pinball game that is hard as hell to beat, but also it's incredibly fun. The stages are interesting but also frustrating, and the mini games that happen can kick you in the ass. If you're playing this on the Genesis Collection with a save state/rewind ability, then the game is a hell lot more bearable.
Regardless, I loved the game as a kid, still love it as an adult, no matter how glitchy it is.
