Wow!! The soundtrack is phenomenal: a nice mix of soothing jazz and bittersweet synth. The upbeat tracks capture that "good day feeling" well, and the melancholic tracks are a great fit for the exploration of purpose. I will certainly look forward to your future composition work!
I liked the story! The main three characters balance each other well, and Kishimoto's gradual drift towards connection and friendship is heartwarming. The prose is good, and the fantastical elements are a fun addition to the game's themes.
My only negative note is that the ending was quite baffling to me; the stakes seemed a bit extreme, and I'm not sure how well it fits with the rest of the story.
Regardless, I really enjoyed this kinetic novel. It's a fantastic showcase of your skills as a composer and writer.
Great work!
