Hey Bonsix! You definitely nailed a thriller/horror vibe for your OST. The tracks are very cohesive and is dark which goes along with your concept. My favorite song here is Viral Reality. It felt like a nice introduction to the track and the game concept. Your stage music definitely pushes the feeling of being chased. I think if the sections within those songs were more different, it would contrast well and keep me hooked.
Spooky work and love the concept!
