I didn't get that far because I'm not very good at platformers, but this is a really good concept and an interesting execution. Being the person I am, I always chose what I thought was right regardless of how it would effect the difficulty, which is maybe part of why I didn't get that far.
It was kind of creepy and thought provoking, which is I think what you were going for. You may not have been able to do everything that you wanted to with it but I think what you did do was really cool.
