Simple concept but executed well for what it is. 

I would have liked a bit more variety, perhaps a difficulty increase, different falling speeds, different leaf behaviours, perhaps augments that make you larger or faster, anything in that vein could work I think, if you plan on adding more.

Anyways, thanks for sharing

Honestly, kudos for going no engine. That in itself is a great feat!

Nice job! I thought the visuals were good and the gameplay loop was easy to understand and play. I found the game to be pretty easy and I stopped my game after collecting 50 leaves. I'd be curious to see how your game would play differently with more variation in the leaves movement; more erratic movements as the player got further in the game would really help to give your game more of a difficulty ramp and make for a more interesting game.

games really hard but also really fun!
