Got the carrot!
Charming, simple yet so effective. The visual style is such a great choice for the jam, allowing you to create something fast yet with complete polish. The puzzles had the perfect quality of looking obvious at first, leading you to a dead end, and then giving you that "aha" moment.
One thing I'd change is to say "stretch" the boxes instead of "pull" the boxes. I didn't realize you can compress the boxes down until the very last puzzle.
