Creative idea with a falling leaf, I liked it. Also the soundtrack and animation of the leaf are pleasant.
The only thing, it seems to me, is that the leaf is somehow difficult to control: it is not always clear how far the leaf will fly if the wind is passed over it. Also it’s not entirely clear how big the wind’s hitbox is, sometimes when I wanted to push a leaf to the bottom of the screen, I tried to move the wind past it, but I accidentally touched it and pushed it up.
Overall the game is very creative and interesting. If you improve the wind logic, it will be absolutely wonderful!
