Great work for being limited to 30 hours only! Each track brings it's own uniqueness and keeps you guessing in a sense. I do have one small critique to add tho and that is I feel as if the tracks are somewhat repetitive in nature, but that's understandable since you had such short time to create the OST (and plus, my OST is probably more repetitive anyways lol). Everything else from the sound design, use of instruments, and atmosphere I love tho!
My favorite song would definitely have to be "Inside My Comfort," but that's probably because I love well done calm and peaceful tracks. Although all the songs are great in their own way regardless!
Overall just an impressively done submission for just 30 hours, equipped with some creativity and uniqueness!
That's all I have to say really, have a good day :D
