Neato! I love the concept, I like the idea of teleporting to the spot you picked in the mirror you have.
Like a few of the previous comments I also had problems with the controls, it was pretty hard to move around. The platforming sections during the fitness training will probably less frustrating than it have to be after those get fixed.
Also like Felix from earlier I also ran into the bug where you try to teleport into spikes and you get stuck in an infinite loop. A way to manually restart the room would solve this, I believe.
