I.M. Meen is a 1995 fantasy educational game for DOS to teach grammar to children. It is named for its villain, Ignatius Mortimer Meen, a "diabolical librarian" who lures young readers into an enchanted labyrinth and imprisons them with monsters and magic. The goal of the game is to escape the labyrinth and free other children. This is accomplished by "shooting spiders and similar monsters" and deciphering grammatical mistakes in scrolls written by Meen.
