It is quite possibly the only Oculus-Rift-compatible entry in the 48-hour competition (no other games mention it in their descriptions except for a couple 72-Hour Jam games).
Audio was amazing! How did you do it?
The music I did through my usual music composition software (an older program called Project5, but it’s basically like a tracker). All the sounds were various microphone vocal recordings that I modified in GoldWave to sound more like footsteps, a pistol firing, and so on.
