The gameplay loop is nice, I liked searching for the leaves and I think you did a good job with the colors and the way the leaves move.
The sound for picking up seeds was quite loud, making me jump and hurting my ears. Music would have also been a nice addition, and maybe some sounds when pushing the leaves around as well.
I also had some trouble navigating as I had trouble remembering where I'd been since every area looked similar, I think adding rocks, trees, water, etc to distinguish each area could help a bit.
Your game for sure gave me cozy fall vibes though, so nice work.
