Had this game when I was a kid. Funny story, I put in a random password that came to me in a dream (6718) and the game put me in this fucked up level where Jerry was floating in space and had to run from the all-consuming green void, and I kept repeatedly dying despite my efforts, the level just seemed to go on endlessly

Scared the shit out of 5 year old me and nearly made me tell my mom to give away all my games (including my Pokemon games). I wonder how much more successful in life I'd be if that actually happened, but at least now I still own those $300 worth of Gen 1-3 Pokemon games
