Incredible clarity of design and a tasty meme. When you finish each "world" gratification comes in form of both the knowledge that you have conquered yet another devious set of puzzles and a little tune that vaguely reminds me of that youtube video of some nerd playing the Titanic theme on a recorder. Will constantly surprise you not only with how many ways there are to manipulate a sausage (hur hur hur) but also with how many ways there are to fail a level. Quick, infinite undo button allows you to experiment wildly on each level, which quickly teaches you that rapid-fire trial and error will just make you get it completely wrong a lot faster and haha no you really have to use your brain, good luck, this game is 100% idiot-proof.
