That would probably be “Maze of Galious”. It’s one of the first games ever I got really into and played through a million times back when I (or rather, my father) had an MSX computer. I was still a little squirm back then, and I’m so sad that my mom got rid of the computer after my dad left. I downloaded the game and an emulater for it last year and played through it again. I seriously never wet my pants so much in happiness of how awesome the game still is.
