I don't understand why I can pick things up if I'm not gonna use them.
It would be nice if when you pick stuff up it goes into different slots and you could choose what to try to use each time, like dragging and dropping from your inventory or maybe clicking to select in the inventory and then clicking the scene.
It would also be good to be able to go back and pick up things you might have left behind, since I got to the top and I could neither go back nor do anything except click the plant until I "die", unless that is the intented ending, which isn't satisfying at all. Maybe have the head of the plant need some water and you take it up to her and then she thanks you before you wake up?
