I like this one! I think it could use an upgrade like "click radius" that lets you pick up multiple at once. Also you may want to tell the player they can click and hold to pick up (or better yet make it an upgrade). Some audio each time you pick up a leaf would also be nice feedback for the player. I think this would benefit from an intermediate step as well (to which you could also apply upgrades). Something like Leaf It Alone makes you pick up then bag the leaves before you can turn them in. Something like dragging your leaves to a bag would have maybe been good here because then you can build on drag speed, number per drag etc. But overall nice job. Good cozy vibe as well.
