The change of pace and tone in BLUE is welcome and bring a good dynamic. I felt instantly carried away in the mind ocean of this game when it happened.
DIVE felt like a joyful adventure after the contemplative opening. The mix of major tone melody with the "spanish cadence" around 1.00 (it's how I name it ^^) helps to convey the idea of discovery and wonder within the adventure.
WAVE was a fun break. I love those kalimbas sound! It evokes The Little Mermaid :)
Again, FLOW gave me an animated movie vibe! Maybe the combo of choirs and Bell sounding instrument.
SINK really was entertaing and interesting in its mouvement. I see it as a couterpart of DIVE. It hit me with the rythm before making a link with the title :) (i have to be honest, I just read the game description and didn't go on track detail you provided :( I might give it a shot after the jam... blind listening with the main idea is cool though)
DEEP : oh the first real threat is coming.. I like that I can just listen and understand what is going on. I mean this one is obvious but still, there is a story ongoing in my mind right now.
BREATHE made me feel like I was still deep beneath the surface but protected by a big bubble in which I could breath and rest after the previous challenge.
That was a great musical narration where I could still recognize your style. Well done Mr.Blue Lava :)
