Track 1: Definitely a very creepy, unsettling opener... do I hear a bit of Dies Irae in this melody? Always a good touch ;) this track did run pretty long, though I'm assuming it just loops, so I ended up cutting to the next one around 3 minutes in to save time.
Track 2: immediately, I was impressed by the use of synthesizers here-- and it sounds like you've incorporated the main theme of the first track here. The monster-breathing effect was brilliant. This becomes incredibly eerie very quickly... the mixing is so immersive.
Track 3: another cool-sounding track, and quite cinematic-- I enjoyed the sudden dramatic shift. You keep interpolating that me-di-me-re motif everywhere, it's very cool to keep hearing it pop up! However, I again had to skip forward as this track was a little repetitive after a while. Try to avoid getting locked into the four-chord repetition cycle, it can take away the natural momentum of a track!
Track 4: loved the electric guitar entrance! Is that you playing? This is another really cool track at first, and then it gets locked back in to a repetitive pattern-- after the 14th or 15th repetition, the piano motif is becoming redundant.
Track 5: super hardcore track-- I am really digging this electric guitar! Your composition skills are really good, each track is well-crafted and I am still hearing that motif everywhere.
Track 6: You have an excellent way of making twisted, corrupted-sounding music-- and I love what you've done with this track. The restatement of the first part of the track, now with a corrupt thundering sound beneath it, is a cool effect.
Track 7: more good stuff, nice job here. Also, I just saw your note on the repetitiveness of these tracks-- so I take back my previous criticisms, sorry about that!
Track 8: still loving all of the hardcore stuff you're making! This is an awesome "final chase" theme.
Track 9: Again, cool stuff here-- I love all the story cues you have. Each track is very well-curated to match the story, you have a great intuition for that.
In all, this soundtrack is immersive, eerie, and remarkably well done. Amazing job, and keep writing!
