Fun little platformer!
The wall jumping feels really good, I really liked just jumping around in those upward paths.
I also really liked the art you used for the sky, it's simple but looks very nice.
A few problems I had: The performance isn't great in the web build, the tree climbing was a little fiddly especially in the section where you are going between the trees over spikes.
But on the whole, great work, really enjoyed the game!
