Pretty decent little game you made, the falling animation at the beginning was really cute. I though the movement where the character jumps while moving left and right was going to be interesting, but unfortunately it didn't really have any impact on the game at all as I was mostly only moving left and right while jumping anyway. Would be cool to see this have better use. I got stuck in a section where there were literally no leaves that I could jump to - they were all too high and I fell to the ground, which felt a bit unfair. The concept itself is okay, it's similar to many other games like doodle jump but it had a nice theme and I like how the leaves float from side to side, so that's a good twist.
If you do end up making it a full game, it'd be good to see some temporary powerups in a run or something like that, maybe some obstacles to avoid like bees or something.
Overally, great job and keep up the good work :)
