XOR

XOR is a logic-circuit construction game about building computers from the ground up. You start with almost nothing: wires, switches and basic logic gates. From there, you build.

 AND.

 OR.

 XOR.

 NOT.

 Then things get bigger.

 ADDerS.

 REGISTERS.

 ALUs.

 MEMORY.

 CPUs.

 Your goal isn't to finish a list of traditional levels. It's to understand the machine you're building. Build a circuit. Test it. Find the problem. Fix it. Make it smaller. Make it faster. Then use what you learned to build something even more complicated. XOR features:

 • Build circuits on a large grid-based workspace

 • Connect logic gates and electronic components

 • Run and observe your circuits in real time 

• Construct adders, registers, ALUs and CPU-like systems 

• Electrical components can heat up and fail

 • Contracts with truth tables and gate budgets

 • Progressive technology eras

 • Achievements and unlockable components

 • Save slots for your creations

 • Export your circuits as editable .xord files and .obj drawings

 • Retro computer / CRT atmosphere The long-term idea is simple: WIRE → LOGIC → ADDER → REGISTER → ALU → CPU → MEMORY → COMPUTER 

How far can you take it?

 XOR is still evolving, and your support helps fund development toward the full Steam release.
