Soundtrack composed by Gordon McNeil
Check out that MIDI rock music! Oh yeahhhh... as mentioned before, I never got that far into Cthulhu Saves the World but hey the little I played was fun and its sountrack was pretty memorable. This music plays when you're in combat towards the beginning of the game. It's ever so dramatic, heroic and a bit of a headbanger.
The soundtrack is available for free off Gordon McNeil's bandcamp page but I'd highly recommend paying a dollar or two for the soundtrack if you're a fan of the game. It's also available off the Free VGM section at Choicest Games.
