Atomic Test Pilot

Soundtrack:

Atomic test pilot's OST featured new music from springloaded's punk rock alter-ego Sludgefeast. The game features instrumental versions, because the vocals tend to be somewhere high up in the regions of pointless swearing.

The game fatures a mode where you can play with just sound effects, in reality these sound effects are notes that are affected by the speed of your ship. The only way to hear these is to play the game (as they are pretty pointless on their own, although "the end of everything" gives you an idea of how they work.
