Thank you so much for your detailed comment! The dryad has a set path, and the level will end when she gets to the end. You guide the creatures to the lamps (they should stay there) which are on her path, and she will pick them up when she passes by. In hindsight, I should have made some simpler levels before the garden! (I ran out of time for the forest, so it can't unlock) I will check out your game as soon as I can.
oh! You might have noticed by now but I was not a submitter to this jam (although I am a dev). I have a friend who was in the jam so I'm doing my due diligence to rate several games and not just theirs haha. If you wanted to check out my friend's game though it's this one! https://itch.io/jam/thatgamejam01/rate/4171954
