Neat idea !
Few feedbacks: restarting from level one when you fail is very frustrating.
You kinda stick to the walls (easy fix on unity is to add a physic2D material to you player and set friction to 0) or if you want to keep it maybe add a wall jump ?
The reality change thing wasn't really clear (still not sure what it does exactly) you should explicit that in game or in the page desciption.
Apart from that pretty neat game. good work :)
