Instruments: Synths
Tempo: 89

This a simple "fake bit" composition. I used very simple oscillators for everything, and then processed it quite a bit. Made for a dungeon level for an old-school video game. Loopable. Video Dungeon Boss is similar but faster. ISRC: USUAN1200064 029 Dark, Humorous 2012
