Tried playing this in windowed mode first and my character was running at 1/8 speed even though the animation was running at normal speed. I had to reload the game in full screen to play. Later, I fell and saw the wall approaching from behind. Quickly, I started teleporting like crazy to get away and it was a straight shot with no obstacles. I don't think I was supposed to be there. Eventually the floor ended and I began falling endlessly into space. Gonna play it again because the concept and visuals are so fun.
*Edit: I beat it. I recommend having a cool-down timer on the teleport, maybe with the option to string together teleports if you time the teleport properly. I didn't even see the last portion of the level because I literally teleported right over it. I have no idea what could've been down there.
