I.M. Meen (1995)

If you're going to make a grammar and spelling edutainment video game and have no idea how fun works, follow the example set in I.M. Meen and rip off the best intellectual property you can find. In this blatant DOOM clone, you play as a child who's been kidnapped by a giant-headed lunatic (the eponymous Ignatius Mortimer Mean) and locked in a labyrinth filled with monsters from classic horror fiction. Use magic wands and explosive fruits to blast your enemies out of your way, strafing and dodging as best you can! Unlock heavier fruit-based firepower by spellchecking the large blocks of inane, badly-written text that locks vault doors! Have the goofy theme song get stuck in your head for nearly two decades! This is about as bizarre a find as that Chex Quest dealyhoo I found in my breakfast cereal around the same era, but with an arguably better moral.
