## What it is
Crown is a complete, cross-platform, open-source game engine written in C++ with Lua scripting, featuring a full level editor, asset pipeline, and sub-second hot-reload for fast iteration. It targets Linux, Windows, Android, and HTML5 with a performance-first, data-oriented runtime.

## Use cases
- build a 2d or 3d game with an open-source engine
- game engine with fast hot-reload iteration
- cross-platform game engine that exports to html5 and android
- script game logic in lua with a live repl
- self-contained game engine with no account or internet required
- hackable game engine with text-based project files

## When to choose
- you want a free, permissively licensed engine with a complete editor and deployers
- fast iteration matters - everything hot-reloads in under a second
- you need to ship to desktop, Android, and HTML5 from one codebase
- you prefer data-oriented design and a simple, hackable runtime

## When to avoid
- you need console (PlayStation/Xbox/Switch) export
- you rely on a huge asset store or large community ecosystem
- you want a visual scripting-first workflow rather than Lua/C++ coding
- you need extensive third-party plugin support
