Hamiltonian Circuit

You have been hired as an intern at an untitled company! Your task is to build electrical circuits using pieces of wire provided by the company. Unfortunately, the wires haven't been cut properly and it is now up to you to turn them into complete loops.

About the Game

Hamiltonian Circuit is a puzzle game about building electrical circuits following a Hamiltonian path. It was made for the GMTK Game Jam 2025 with the theme "Loop".

Your goal is to connect both ends of the battery with a wire that visits every space on the board exactly once. This means that:

• No empty spaces should remain in a complete solution
• The wire must not cross over itself

Controls

• WASD/arrow keys to extend wire in cardinal directions
• Space to undo last placement
• R to restart from battery

Tools used

• Godot 4
• Aseprite
• Audacity
• Paint.NET
• Blender
• Soundtrap

Assets

I made all of the game's assets (almost) completely by myself except for sound effects.

I used CC0 audio from freesound.org which I then edited in Audacity.
