This was great!
I loved the general vibe that the music and visuals created.
The controls and animations felt really smooth, and there was great feedback for doing actions like jumping, attacking, swimming and teleporting.
The world design was also very nice, it really felt like the world was expanding but also like I was unravelling a big knot.
The only thing I think could've been edited were the controls, I would've preferred using WASD for movement, space bar to jump and M to teleport.
Other than this, this was a wonderful experience! I'm very interested to see if you take this further :).
