This is probably the most interesting soundtrack I've come across thus far. It's incredibly chilling.
The heavy use of percussion on "Fightflightorfreeze" is insanely memorable and my biggest highlight across the whole OST. I'd love to play a game that uses a unique style like this for it's battles or even as a chaotic dungeon theme.
The whole soundtrack manages to capture anxiety in a vivid way, and it's somewhat terrifying to listen to. That's very hard to pull off. Amazing work
