Congratulations on the solid submission! Really interesting concept for a puzzle game and very distinct gameplay.
I found the Plorbs difficult to control on the second level, as it seemed to make some interesting decisions about which Plorb to focus on as the main one being controlled. I think the idea controlling all Plorbs at once is interesting but its execution was just a little off in my personal opinion; I'd rather have only controlled Plorbs that are attached to the Plorb that I'm controlling, though this may have made the puzzles too easy perhaps.
A little bit of background music may have enhanced the experience, but I appreciate the time constraints of the jam and the gameplay is more important (something I kind of failed with myself haha).
Great work, and there is a solid idea here to build from if you wanted to.
