Awesome level. After my first few attempts and being 6 off, I figured there had to be something I was missing. After a little more stumbling around in the level I happened across the right idea, and managed to get it. Very nice one.
Interesting "which side do you pick to do first" mechanic. I think I have a lot more respect for this kind of level design since I made my old review in 2008, so I'm updating this to a 5/5. Still not the best ybbun level but the pathing options are good.
