Halley is a lightweight, code-first game engine written in modern C++17, featuring a true entity-component-system architecture, modern graphics pipelines, and hot-reloading for fast iteration. It was used to ship the commercial game Wargroove on Windows, Mac, Nintendo Switch, Xbox One, and PS4.

Use cases

• build a 2D or lightweight game in modern C++
• ship a game to consoles like Switch, Xbox, and PS4
• use an entity-component-system game engine without a heavy editor
• get hot-reloading for fast game development iteration
• write a code-first game engine project with first-class shader support
• add Lua scripting to a C++ game

When to choose

• you want a modern C++17 engine with proven console shipping experience
• you prefer code-first workflows over editor-driven ones
• you need a high-performance ECS architecture
• you want cross-platform support including consoles

When to avoid

• you need a full-featured visual editor like Unity or Godot
• you want a beginner-friendly engine with extensive tutorials and samples
• you need to support legacy platforms like Windows XP or old mobile devices
• you prefer engines with large asset store ecosystems
