Notable Features

Some of the music tracks incorporate themes reflecting the structure or gameplay of the land(s) they're heard in.

Geometry

A piano reproduction of the 6/7 pattern of the Icy Land music.

The very first piece of music heard in the game, that of the Icy Land, has a beat pattern that alternates between 6 beats and 7 beats per standard interval of time, reflecting the Hex-Hept tiling of the standard game.

Shepard's Tone

Heard in Whirlpool, R'Lyeh, and Temple of Cthulhu, part of the music incorporates the 'Shepard Tone', reflecting the infinitely nested, self-similar structures of Whirlpool and Temple of Cthulhu. ("The player can descend forever without anything changing")

The music overlaid with its time-reversed counterpart, demonstrating global symmetry:
