By Toby Fox

Surprisingly complex. The main melody’s done in chiptune: slow main theme, fast backing beat (one that translates really well into a heavy-metal guitar chug). Around the ten second mark, a light orchestra’s worth of natural instrumentation kicks in. It gives the song its ‘this is really it’ final-boss vibe.

Only this isn’t it. Not quite, anyways.

The soundtrack to Toby Fox’s game Undertale can be purchased from Bandcamp.
