These last few days, most of the people I know’ve been playing Manufactoria, a game revolving around fixing up robots in a turing machine-esque manner. (If you’re at all into programming, I suggest you check it out. Also, rate it high!)
Quickly, one starts running out of levels to solve, however, so I’ve decided to make a small collection of additional levels you can play. Mind you, I have not solved all of these myself, so the unsolved ones may very well not be solvable in the space allotted. Caveat emptor.
