Firstly, I appreciated how fleshed out your game and soundtrack explanations were. It helped a lot to understand the meaning behind everything.
This submission is lovely! You did a great job with how you handle the rising and falling of energy and tension in each track. And each track has its own identity while still keeping the whole submission cohesive, which made it much more interesting to listen to.
The one thing I would consider is reverb levels. At times, there tends to be a lot of instruments fighting for the "closer" spots (i.e. little to no reverb). I think giving more instruments a little more space would go a long way. Great work!
