Though I love the puzzles, as soon as the "whole machine" cell comes in, things break. Signals didnt go to where the arrows pointed so I couldnt play any further than that. I think it's great you could make so many levels, but im not sure it was the best idea to go with, since an out of control puzzle is hard to make interesting. Definitely annoying when you plan something that should work but it doesnt because a cell shows random behaviour.
