Managed to get all the leaves, and I think 4 out of 6 golden leaves.
Gameplay wise, it's a classic platformer, decently executed. Perhaps a few quirks here and there for ground detection, but it's fine. The 'intentional bugs' were most of the time pretty clever ;).
A small negative point for me would be the music. It kinda drilled my ears after trying to collect all the golden leaves.
