## What it is
high_impact is a 2D game engine written in C, designed as a framework for building action games like platformers, twin-stick shooters, and dungeon crawlers with a focus on pixel art. It compiles for Linux, macOS, Windows, and the web via WASM, using SDL2 or Sokol backends with OpenGL or software renderers.

## Use cases
- build a 2d platformer in c
- make a pixel art jump'n'run game
- create a twin stick shooter
- build a top-down dungeon crawler
- compile a 2d game to webassembly
- make an arcade game with generated music

## When to choose
- you want a lightweight C framework for 2D pixel art action games
- you need to target desktop and web (WASM) from one codebase
- you prefer a code-first engine that calls you rather than an editor-based engine
- you want a small, readable codebase (~4000 lines) to learn from or modify

## When to avoid
- you need a general purpose engine like Godot, Unity, or Unreal
- you require extensive documentation or a large community
- you need to load common asset formats like PNG or WAV directly
- you want a standalone library you can link into an existing project

## Facets
- artifact type: framework
- maturity: experimental
- function: game-engine, graphics, audio-processing, image-processing
- domain: cross-platform
- platform: windows, wasm, cpp
- tags: 2d-games, pixel-art, c, sdl2, sokol, opengl, software-renderer, qoi, qoa, game-development, linux, macos
