Criminally underrated entry IMO. Some of the vistas in this game where really stunning, the music was beautiful, the controls where snappy and everything just works.
The progression was thoughtful, you placed the Powerups at a reasonable places and locked progression just the right way. I particularly loved how each area had a theme, if intentional or not. Howling in the Forest, Strength in the Mountains, Agility among the Treetops and Sunlight at the highest point!
Sadly those "Spirits" where quite small, they looked pretty funky and I wanted to see them better.
At first I was quite surprised by the fitting theme song playing during the Intro, it took me by surprise that it both works for the Intro and Gameplay so well, even though it's just a Piano.
If I didn't see you submitting 1 min before Deadline, I'd say you have worked on this for more than 48 hours but damn. Great job if you did.
Btw. I read those comments about the Walljump and I had that problem the first time in my playthrough as well. It doesn't work as it does in other games. But honestly? In my second go it kinda clicked and felt rhythmic and right. And the animation on that was really satisfying.
Wished for some more sounds. I liked what I heard!
