The OST for my latest game "she danced in the wind like a holographic dream before the world died" features otherworldly dark ambient soundscapes.
Although the project uses a lot of procedurally generated audio, there's also classic ambience work, now featured in this OST.
"she danced in the wind like a holographic dream before the world died" is a short game poem and interactive fiction about The End, in which you play the last flower left on Earth.
