## What it is
Tetra is a simple 2D game framework written in Rust, using SDL for events and OpenGL 3.2+ for rendering. It offers an XNA/MonoGame-inspired API with batched 2D rendering, input handling, and a deterministic game loop.

## Use cases
- build a 2D game in Rust
- make a simple 2D game with SDL and OpenGL
- XNA/MonoGame-style game framework for Rust
- render sprites with draw call batching
- handle keyboard, mouse, and gamepad input in a Rust game
- create a deterministic fixed-timestep game loop

## When to choose
- you want a simple, lightweight 2D game framework in Rust
- you prefer an XNA/MonoGame-inspired API
- you need a deterministic game loop and built-in font rendering, cameras, and screen scaling

## When to avoid
- you need a framework under active feature development - consider macroquad or ggez instead
- you need 3D rendering or a full game engine
- you require guaranteed bug fixes or new features, since the project is only passively maintained

## Facets
- artifact type: framework
- maturity: maintenance
- function: game-engine, graphics
- domain: -
- platform: cross-platform, rust
- tags: 2d, sdl2, opengl, gamedev, xna-inspired, game-development
