Well, this idea is very simple but also very creative. Basically it inverts the control of the knight and adds two additional characters to watch out for.
At first i had the problem that i saw everyting as an obstacle, such as the red boxes and the chains too. With later levels i had to stop at some point, because it was just too difficult to pay attention to three characters at the same time.
Despite that i think this is an amazing submission. My respect, great work!
