I had this game on Game Boy. I did not buy this game on Game Boy. I'm pretty sure a classmate straight-up gave it to me, and I'd say they got the better end of that bargain.
It's like... you start in a hallway, and walk to the right. Well, shuffle to the right, fists raised. You slapfight one enemy. The hallway ends. You're supposed to pull off some arcane fighting-game special move to grappling-hook to the next floor. But the game doesn't fucking tell you how to do it, and isn't great at detecting inputs anyway. So I have seen the second room of this game maybe twice in my entire life, after dozens of bored afternoons sticking random games in my handheld in pursuit of low-stress fun.
90s kids did not have the Steam library problem, where you scroll through a thousand games and go 'ugh.' At least not until the 2000s when Flash caught on. Whatever physical software you owned, you tried to make work. I got most of the way through fucking Hydlide... in 1997. So I'm not sure anyone under 30 understands the gravity of one child just giving away a whole-ass video game on the playground. Either they're an innocent idiot who will come to learn regret, or else they're passing on a curse.
