Very interesting, very fun concept! Personally, I would improve the difficulty curve, start with one color then add more.. especially as there's some learning involved. Nevertheless great use of the theme, and such good music to go with it!

Tbh, It's actually really hard to get right, esp in a jam. Since you are building the game you're an expert with the controls lol, and the jam voting becomes the playtest. 😅
(Not that it matters, but funnily one of the first games I ever built, but didn't ship, was a game where when you press the screen and a diver goes down and you side scroll through an underwater level.. similar to your game. So I know personally, this mechanic is just hard to get right for everyone's reflexes. Nevertheless what you built was fun and you innovated really nicely with the loopiness :D )
