This file is not a game, but it IS a sound track for a game!
If you like almost-chip-tuney video game musics, you might enjoy this bunch of MP3s! It includes all of Tetracosm's sound track, uh... checking... 38 Tracks that are actually music! Cool. Includes the other ambiance-not-really-music stuff too if you're into that sort of thing.
These files have been lovingly crafted, modified from oggs to MP3s and built to not loop for practical listening! Enjoy.
And check out the game if you're curious.
