ABSOLUTELY BEAUTIFUL. I definitely love the main menu theme the most because of the addition of water and bubbles. It played so well with how dynamic your sounds were later on in the track. IT ALSO REMINDS ME SO MUCH OF OCTOPATH especially when it starts to build up. My second favorite would be the Credits because I just love the melody. Amazing quality and work throughout. You mentioned it being rushed towards the end but from my perspective, the quality was still maintained until the end.
I definitely want to listen more of all of your works!
