This was a cute, fun, game! I would have loved to see it developed further (the downside of game jams, I say this on almost all submissions).
Fun: I liked the concept, but didn't know the "why" of catching the stars. I died really fast when I didn't catch one star but I think they were physically too far apart at the speed of the platform to catch anything so the fun was short lived.
Theme: I didn't really know what the theme was.
Aesthetics: everything was really cute! It gave bubble-guppies vibes.
Music: I could tell this was stock music, so no worries at all! I feel that the stock could have been picked better though — the music felt a bit like a corporate training video. Development wise though it came through clean with no audio cuts or weird sounds!
Story: from as far as I could tell through gameplay, there was no story
