Personally, I don't like the pack. I know you spent mcuh time on them and some ideas (Limbo, functions) were good but I didn't have fun to cruise them.
I give 4/10

thoroughly unenjoyable indeed. aside from the vsync mess-up parts, all the levels were filled with annoying killer traps and such that made them not fun to play.
