RetroActive: Elf Land
Elf Land: Gorgimers Castle was an independent shareware game for home computers in the early 90s. Help Elfie (or Elfita) find a solution to the Troll problem and save all the Elves! The original developer also remade the game for Xbox Arcade but I suggest avoiding that ugly thing. Though his site does still offer the second half of the original game!

Barely played any DOS games, but it certainly doesn't look half bad---especially for an indie game at the time. Although you're right....that music WILL drone into your head!
I did too, it took me some good digging to find it years later.
I forgot about this game, I owned it when I was a kid!
