This was going to be my Super Western Cowboy entry for the NES game Super Russian Roulette a couple of years ago. I made an IT prototype, but then I abandoned it due to FamiTracker being a requirement, and I have a technique that is outright incompatible with it (namely my cheap DPCM kicks, which use small samples and a pitch envelope). Every other one to my knowledge was met (and the 24KB limit was the reason why the song is a little short, due to getting a bit carried away with the DPCM).
