There are very few games that leave me wanting to do more when I finish them. As the game ends, you will mostly rely on work you have made before. It is really illustrating on how such an iterative process technology can be, and really left me humbled on what a wonder of human ingenuity a CPU is.

The game is capable of giving a really nice understanding of the innards of a CPU in under 6 hours, while forcing you to really understand the labour of every single component. I've had courses in college that failed to do so even in 60 hours.

That said, recommending this game is somewhat difficult for me. Have you studied logic (knowing Morgan's laws will help you down the first steps), engineering or programming, or have any interest in those? This game is for you. But arm yourself with patience, and, if you despair, take into account that since the first logic gate(based in electrical relays circa 1890) to the first CPU passed like 60 years, and that, even with directions, you are attempting what simultaneus investigators took a lifetime to unravel. Be patient and go get a notebook!

Me myself, being a programmer professionally and a gratuate in electronics engineering, have really enjoyed the game. Though, if I had to critique something, that would be that I found the text editor somewhat limited and cumbersome and sometimes the reference truth tables left some space for ambiguity.

Regardless, I enjoyed the game, even with its limitations, it does what it intends quite nicely. I can't wait for more levels, and to be able to program the CPU (A man can wish)!
