This is a really fun and sweet sounding soundtrack! The bubble tracks indeed sound very bubbly- great choice of instruments there. Dash to the Docks is also quite upbeat and catchy which is perfect for a racing theme. I like the idea you had for your game and you definitely represented it well with your soundtrack! 

Harbor Town: Great opening to set the scene. The piano work is very well-performed. Oooh I love the B section at 0:40 especially the roll with those colorful chord extensions. Town by ocean vibes are clear in this track!

The Ocean Spirit: The delayed mallets and the deep ambience give a really nice calm ocean ambient vibe. I like the personification of the ocean spirit through the high piano melody that slowly comes in as if the spirit is shy at first but then is ready to play.

Dash to the Docks: The drums and fast piano melody make for a fun level in your game and have me in the mood for a race! The use of 7ths is another creative way to convey the sense of racing which is used in a lot of Mario Kart track songs - nice!

Until Tomorrow: The bouncy mallets once again evoke the image of spending time with the spirit like from your second track, but the descending harmony helps convey the sense that time is running out or the day is coming to an end.

Overall: Before I even read your description, I could sense your inspiration from Totoro and/or Ponyo right away by the title and the first moments of you soundtrack! I really like the variety you’ve included here. I think that Harbor Town is my favorite - it’s clear to me that piano is your instrument of choice and the results are great here! Nicely done - thank you for sharing!

I really like your 2nd and 4th bubble-themed tracks, I am a sucker for ocean melodies and the bouncy underwater ambient vibe is the most evocative of a consistent theme for me. The third song definitely sounds in line with a racing theme, almost like a frantic course theme in Mario Kart. Great job!

Sweet OST, very bubbly with some variety. Mix is decent the thing I would look for is probably the Piano playing especially in Harbor Town is sounds like it was MIDI programmed with all the high velocity to all the notes, you probably need to play with that to make it sound a bit more humane.  Good job !

Harbor Town is a completely insane, dynamic and fun game on... piano? Awesome!

The Ocean Spirit (Bubbles!) - Nice echoing, mesmerizing ocean effects and... BUBBLES!

Dash to the Docks - I'm feeling the dynamics, a little grace and OOHHH I'M GOING VERY FAST.

Until Tomorrow - Sounds sad( I feel a "drowning" nostalgia for something...

Overall - it was a short and full of emotions adventure.... I enjoyed it!

Thank you)

Nice soundtrack overall, sometimes a tiny bit too much reverb, but good ideas presented well. Cool work!

Dash to the docks was quite fun! I think something that would elevate your music a lot is to play with dynamics or velocity a lot more with your melodies since everything stays at a pretty consistent volume.

Very good soundtrack, I loved it! The song "The Ocean Spirit" and "Dash to the Docks" were my favorites, but the entire soundtrack itself sounds great!
