Rain World Soundtrack - Alphas, Gems, and Junk
About this game
Tracks from the development of Rain World that were never released 'officially'!
A Note from the Developer:
Most of the early tracks were written for the Rain World alpha, which was conceived in a more uptempo, noisy percussion chiptune style that we wound up moving away from as time went on and we got more emo and dreary with it. Some real gems in that batch though, especially RW_4, which featured heavily in trailers and previews early on, but never fit into the game proper.
Also the latter part of the named tracks feature a couple of choice pieces written by Lydia, my absolute favorite of which is Swaying Fronds. That section is pretty solid, just didn't fit the pacing of the original OST release, or the more atmospheric themed "Ambients and Instrumentals" release.
Be warned though: in between those points there is a no-slugcats-land of loud, noisy, junk that was probably cut for good reason! Traverse at your own aural risk!
