One of the best puzzle games I've ever played.

The thing I really appreciate about this game is the degree of difficulty. It's a tribute to how complex things have to be before they can be simple: of how much thought has to go into a plumbing system in order for you to not have to think about plumbing. The tasks the game asks you to perform are all conceptually simple to understand and would be easy to implement were it not for the parsimony of the instruction space in the puzzle system. The difficulty/joy of this game is in understanding how to break these larger processes into multiple (very simple) stages, usually discarding "elegance" somewhere along the way. In any kind of modern high-level programming language the task of reversing a list is usually as simple as typing something like "list.reverse()" but in Shenzhen I/O reversing a set of data requires foresight and planning. In Shenzhen I/O your code paths are literal paths. Enormously recommended.
