Amazingly tight atmosphere here, it really felt like autumn with its mixture of warm and cold trough the music and colors. The adorable little jump sound is just the best, especially in combination with the music^^
The slow movement of the trees really helped to make it feel alive and breathing, it also gave it some element of planning to it as I often wanted to use these slow movements to get to leaves more easily while they swing down. Trough all of this the Character feels amazingly fluid to control and the platforming itself grew very smoothly in it's difficulty.
My only complaints is hat I was often unsure at which Point the player character counts as "on the leave", which lead me to fall into my death several times.
Overall, an awesome piece of work.
