Wonderful set. I solved all but one level.
#1: This one was very reminiscent of Joshua Bone's variety levels in late-CC2, which were among my favorites of the main game. Great applications of the new tiles.
#2: Personally, I thought this was short enough to be somewhat enjoyable, but I could see other players hating this one
#3: Wonderful concept and just the right length and difficulty.
#4: Haven't solved this one, due to the ghost room. If and when I solve it, I don't think it will be among my favorites. The mimic room feels a little uninspired.
#5: A really neat dodging level, but I don't feel the grey button part adds much.
#6: Great concept and very fun to figure out.
#7: I assume this is supposed to be a red herring-type level, but I figured most of it out during my initial run. Some of its concepts are clever, but I didn't feel too satisfied after solving it.
#8: Surprisingly enjoyable. Solved it on my second try.
#9: Another great concept and the difficulty is just about right.
#10: Deceptively difficult and definitely entertaining.
#11: Oh man, this level. Finally figuring out what it was actually about was amazing. Great presentation. You may want to fix the middle buttons on the left sides of the OR and AND rooms, which aren't properly wired.
