Turing Complete

In this challenging puzzle game, you build a computer from scratch and program it. It is a journey through the layers of abstractions of the computer. The game begins when you are abducted by aliens who are testing your intelligence, and from here a lighthearted sci-fi plot evolves.

This is a hard game, but computer knowledge is not a prerequisite. The best moments in the game is when the solution to a puzzle makes you realize the deep nature of something you took for granted.
