Turing Complete

It's a fun little game. Or maybe not so much a game as a gameified intro to digital logic design and cpu architecture. I didn't find any of the levels all that hard and the game does a good job of making big stuff by either combining or incrementally adding small stuff as the levels progress. However, I have a little background in computer engineering so your mileage may vary. E.g. I was able to remember how half/full adders are built more or less off the top of my head. On the downside, the game does have occasional problems with level goals or component descriptions being unclear. There's a few "convert between number formats in your head as fast as you can" levels which I hated and found completely pointless. And there's one level near the end which is basically "min/max this down to a certain level or you can't proceed" which IMHO would be better left as an achievement or optional level rather than blocking advancement. The steam description of the game talks about designing fully custom cpus and assembly but, while you can do that stuff, it's not part of the main game. The closest you get is defining a couple of pseudo-instruction macros to the assembly defined by the game.
