The game is very cool, as noted before having ice-like slidey physics in platformers like this can be jarring, but in terms of the level design the game is very cool and keeps you going out of interest of what is higher up on the tree. The graphics are really refined and immersive; there is a lot of detail that wasn't necessary and it's a nice touch! The background having mountains and trees makes you feel like you are in an actual forest climbing the weirdest tree in the history of man and the collectibles are unique. The player character is also expressive and charming, and I really enjoy how well it's masked into the 3D environment despite seemingly being 2D (though it would've been nice to have a more prominent jump animation). The tutorial is also implemented into the tree trunk instead of being an external thing which is really cool, overall great game! I especially enjoy the wider platforms with a hole in the middle specifically to make you fall all the way down, crowned by the bird that constantly circles the tree to poo on your head. Good job, this is one of the best! (And there's already a speedrun community, which is a surefire way to tell that you've got a winner.)
