Well! I wrote a huge comment, and then itch completely ate it. Shorter version:
The three sawblades were fairly frustrating — at first I thought I needed a powerup to get past them, the timing was so tight. Then later the lamp broke, which made the sawblades worse, because now if I missed the timing even once I had to start over completely.
It took me embarrassingly long to find the forest; I'd found the leaf at the castle entrance after getting the double-jump, and that let me see the room above, and I was convinced I could get up there from elsewhere in the castle. Whoops.
All told, 25 minutes to get 100%. I enjoyed it, though, and I'm glad I stuck with it! I know the perils of trying to make a puzzle game under extreme time pressure :) I really liked the map design, and the little peeks at later paths that shared the same screen. A few pretty cute touches, too, and I feel weirdly proud of having grown a little garden... from... magical floating leaves? Yes.
