The narrative/story you have for this game is fantastic! I think each track works perfectly and fits well with your game's narrative. Your composition skills are great and your use of motifs is commendable. Also that penny whistle (or at least that's what I think it was) in "Bubble Reef" was lovely to listen to. I feel like you could further elevate its sound with a little reverb, although this could just be my personal preferences speaking. This is a great soundtrack backed by a really intriguing story. Very very nice entry!
