## What it is
A Unity-based walking simulator that generates an infinite, procedurally generated city using the Wave Function Collapse algorithm with backtracking. It includes a playable demo for Windows and Linux as well as editor tools for customizing module sets and generating worlds.

## Use cases
- explore an infinite procedurally generated city
- see the wave function collapse algorithm in action in 3D
- customize procedural generation rules without writing code
- generate tile-based worlds in the Unity editor
- use WFC as a reference for infinite world generation

## When to choose
- you want a playable demo of 3D wave function collapse
- you need a Unity reference implementation of WFC with backtracking
- you want to experiment with tile-based procedural city generation

## When to avoid
- you need actual gameplay mechanics - it is only a walking simulator
- you need a general-purpose WFC library for non-Unity projects
- you need active development or support - the project is in maintenance

## Facets
- artifact type: application
- maturity: maintenance
- function: game-engine, simulation, graphics
- domain: simulation, graphics
- platform: windows, cross-platform, game-engine
