The title theme is bright and... bubbly, and does a good job of outlining the world you've created. Queen Bubblene is actually mildly terrifying, and I love how you had that bit of text on the video explaining how she was basically taking revenge on humans come out right as "So You've Been Turned Into A Bubble" picks up.
Apparently Queen Bubblene is also not so great of a queen? It sounds like it kind of sucks to live in the ocean kingdom, ngl. "Nonstopped Unpopped" has a pretty cool vibe to it, love the bass progression in this one.
Thanks for turning the brightness up on the ocean floor, that was very kind of you.
The build up on "Octo-Popper Supreme" is SO hype. The main portion of the song is a slower vibe that's pretty cool, but I really missed that bassline from the very beginning, and I feel like the strength and weight that started out the track really dropped off after the opening build-up.
Overall, a very cute soundtrack that did a good job with keeping a consistent sound throughout. "So You've Been Turned Into A Bubble" and "Nonstopped Unpopped" were definitely my favorites for the tension, change-ups in key, etc. The bass was also pretty groovy throughout. The idea of the percussion being abnormal to drive home the idea of a different world was unique, and I wasn't sure if I was on board with it at first. The more I listened, the more it grew on me, and it was certainly an interesting method from a composition standpoint. The animations in your videos have a certain charm to them that went really well with the music, and the text was pretty entertaining throughout (I'm glad the octopus made it.)
Great job overall, you definitely put WAY more effort into this jam than was required. If no-one else tells you this, I just wanted to say that I see you, I appreciate the effort you put into this, and thank you for that, I'm glad I wasn't the only one lmao
