NandGame

NandGame teaches the player the fundamentals of digital logic and computer design through a series of levels that start off by assembling simple logic circuits, (which are then turned into components to use in the next level), and build toward creating a simple, but programmable 16-bit cpu.

Once the computer is built, the game also offers programming levels, which challenge the player's assembly programming skill, teaching them the concept of stack, or how function calling is implemented at a low level.
