Hi there! So of course this would generate a lot of interest but I just to throw my stuff your way just in case. Everything you have listed about the game, and the emotions are definitely up my street, and very it's cool as well.
So I'll provide just 2 links, one is my showreel from 2025 which has various game and film works. The second is the soundtrack (albeit short) for a horror short film called Snare that I composed for.

If you want to get in touch, you can drop me an email at stuartwoolleycomposer@gmail.com. Either way if not me I hope you find someone for this because the concept is really cool!
