Very interesting textures throughout here! I dig the heavy processing present throughout - sometimes you just need to really experiment with different chains to see what sticks and what doesn't.
Noticing an almost motif with the use of the crow/raven cries throughout, which is cool. There is a lot of interesting motion occurring in each track, playing specifically off of the sound design textures and some of the choice of percussion voicing. I feel like I could end up listening to several of these tracks over and over and still come away having heard something new each time around.
I think my favorite of the bunch is the Bonus Level Theme - it has some oldschool 32bit vibes rooting it down. I like how haphazard some of the washy noise sounds are alongside the use of stuttered notes and percussive elements. The bass does a great job of providing a pulse to follow the track along with. It gives me some kind of factory-level vibe, almost like the Cortex Labs in the early Crash Bandicoot games.
Solid work all around! I hope you're feeling better - kudos for getting anything at all out there while being sick. Best of luck!
