This is a game I played when I was about 6, in the wonderful years of the early nineties. I was young when I was a child... Oh wait...
Anyway, the game is an RPG for kids. IM Meen is an evil librarian who has trapped you inside his books. You have to fight off monsters and stuff as usual, but to open doors you need to correct spelling and grammar in a paragraph.
Don't be put off or anything, it's actually pretty fun.
