I'm always down to puzzle games, and this one is great! You had a great idea of using Enderpearl's teleport mechanics to reach unaccesible platforms. But I gotta say... this game is so hard XD
There were places where you had to jump in an exact point, or you would die. I died a lot of times, but I managed to reach the end. Btw, your easteregg made me laugh, nice one!
I would suggest to add at least a pan to the camera, because there were times I couldn't see what was below or above me, so I had to do some leap of faiths, which lead me to more deaths.
Nice and solid entry, congrats! I would love to see more of this game!
