## What it is
olcPixelGameEngine is a single-header C++ framework for fast pixel-based 2D drawing and user input, used in javidx9's YouTube tutorials. It supports game development, algorithm visualization, prototyping, and education across Windows, Linux, and macOS.

## Use cases
- make a 2d game in c++
- visualize algorithms with pixel graphics
- single-header game framework for beginners
- prototype graphics experiments quickly
- learn game programming from youtube tutorials
- draw pixels and handle keyboard input cross-platform

## When to choose
- you want a minimal, single-header 2D pixel graphics engine
- you're following javidx9's tutorial videos
- you need simple cross-platform desktop graphics without heavy dependencies
- you're teaching or learning game programming fundamentals

## When to avoid
- you need a full-featured production engine with asset pipelines and editors
- you're targeting mobile platforms officially (community forks exist)
- you need hardware-accelerated 3D rendering out of the box
- you require permissive licensing for commercial redistribution without attribution

## Facets
- artifact type: library
- maturity: active
- function: game-engine, graphics, ui-components, image-processing
- domain: graphics, education, cross-platform
- platform: cpp, windows, cross-platform
- tags: pixel-art, single-header, 2d-games, javidx9, olc3, prototyping, algorithm-visualization, game-development, linux, macos, desktop
