The one-frame teleport dash is a little jarring, it'd be good to make that movement take place over several frames (you can make the player invulnarable i.e. iframes during the animation to keep the same balance). I did get stuck on a tree early on, but a lot of wiggling and dashing eventually freed me, so it was only a minor issue. I really enjoyed the 2D inside 3D aesthetic and the art style is great!
