❤ Game Concept

This unique puzzle experience challenges players to construct a fully functional CPU from scratch, beginning with a single NAND logic gate and methodically building increasingly sophisticated components. Players wire digital circuits using a custom Hardware Description Language, systematically revealing the fundamental architecture of computing systems.

❤ Core Gameplay Mechanics

Players tackle specific hardware design challenges by crafting logic gates like NOT, AND, and XOR, connecting components through precise text-based syntax, solving design specifications with escalating complexity, and leveraging previously created modules to engineer advanced circuits.

❤ Progression and Learning

The design journey advances through critical stages of basic logic gates, multiplexers and demultiplexers, memory registers and RAM, Arithmetic Logic Units, and ultimately 16-bit CPU construction.

❤ Unique Gameplay Features

Includes an in-game assistant named 'Ted' who automatically scales 4-bit designs to 16-bit versions, a retro 1980s computer terminal aesthetic, comprehensive in-game documentation, and performance tracking via NAND gate count.

❤ Player Engagement Drivers

Designers find satisfaction through incrementally building complex systems, solving logic puzzles with elegant solutions, experiencing tangible technological understanding, and optimizing circuit designs.

❤ Difficulty Curve

Requires logical thinking and systematic problem-solving, gradually introduces complexity, and rewards persistent experimentation.

❤ Typical Player Experience

Enthusiasts typically sketch diagrams on paper, experiment with multiple circuit configurations, debug intricate logical connections, and develop deeper comprehension of computational principles.
