Hello, as someone who has gone through psychosis, I feel that I can write some excellent music for your game. My music tends to be darker, so i recommend listening to it and letting me know your thoughts. vandymusic.com is my website and shows a variety of what I can compose and produce. Feel free to follow the links to my Spotify as well where i have some darker music released that may be along the lines of the emotions you are looking to capture.
