## What it is
Coffee is an opinionated 2D game engine for Rust focused on simplicity, explicitness, and type-safety. It provides a hardware-accelerated 2D graphics API, built-in GUI, loading screens, a debug view, and multiplatform backends via OpenGL, Vulkan, Metal, and D3D11/12.

## Use cases
- build a 2D game in Rust
- make a 2D game with a simple Rust game engine
- create a cross-platform 2D game with hardware-accelerated graphics
- add a responsive GUI to a Rust game
- render batched sprites and meshes in Rust
- prototype a small 2D game with deterministic fixed timestep

## When to choose
- You want a simple, explicit, type-safe 2D engine in Rust
- You need built-in GUI, loading screens, and a debug performance view
- You want multiplatform graphics backends (OpenGL, Vulkan, Metal, D3D11/12)
- You value deterministic fixed timestep and batched draws

## When to avoid
- You need a mature, feature-complete engine - Coffee is in a very early stage with many basic features missing
- You need 3D rendering
- You need long-term stability - the master branch can contain breaking changes and releases are infrequent
- You need a large community and ecosystem

## Facets
- artifact type: library
- maturity: maintenance
- function: game-engine, graphics, gui
- domain: graphics, cross-platform
- platform: windows, rust, cross-platform
- tags: 2d, gamedev, opinionated, type-safety, wgpu, opengl, vulkan, metal, gamepad-support, sprite-batching, game-development, linux, macos
