## What it is
A Flappy Bird clone written in pure C for Android, packaged as an APK under 100 KB using OpenGL ES 2, OpenSL ES, and Android Native Activity. It demonstrates extreme size optimization for native Android game development.

## Use cases
- play flappy bird on android with a tiny apk
- learn how to build android games in c
- minimize apk size for a native android game
- example of android native activity with opengl es
- study how to play sounds and decode pngs in c on android

## When to choose
- you want a minimal-size native Android game example
- you are learning C-based Android development with rawdrawandroid-style tooling
- you need a reference for OpenGL ES 2 and OpenSL ES on Android

## When to avoid
- you need a legally licensed Flappy Bird (original rights belong to DotGEARS)
- you want a cross-platform game engine or high-level framework
- you need a maintained, feature-rich mobile game project

## Facets
- artifact type: application
- maturity: active
