I am typing these thoughts as I listen to the OST.
World of Memory - What an atmospheric opening track! The first half of it has a purely textural vibe that truly feels like you are in the ocean, and then the second half comes in and makes you feel at peace almost!
Colorsplash Beach - Immediately you can definitely feel a very happy and upbeat vibe, a major contrast from the previous track, which was much slower even if peaceful. However, it almost feels too happy in a way, like this isn't the place you really should stay in.
Fight To Remember - Very textural, more similar to the first song than the second! But after a slow and peaceful, yet somewhat melancholic opening, it gets right down to business with the percussion and the other various textures. Various exotic and tense instruments inhabit the middle section, before it slows down once more to conclude the piece and the soundtrack as a whole.
Overall, I really enjoyed this soundtrack! World of Memory is probably my favorite!
