Portal 2 hahaha that's a really cool puzzle :) And a really good game :) <3.

No need hint... logical and very good picture at end.

That was a lot of fun!

Awesome. As coxcox said, the hint is entirely unnecessary. (I think the hint was supposed to say "each" instead of "edge")

This was a triumph,
I'm making a note here
HUGE SUCCESS.

Great!
