VadimBoev’s GitHub project is an Android Flappy Bird clone written in C. Its repository describes an APK target of less than 100 KB and support for Android 5.0 and above; those are project claims, not independently measured size or device-compatibility results. The source and release downloads are hosted on GitHub.
What the project is
The repository describes “Flappy Bird in C” for Android, with an APK size below 100 KB as a goal. It is a downloadable software project rather than a retail game product. The repository’s size and Android-support wording is available in the VadimBoev/FlappyBird repository.
The implementation uses Android Native Activity, OpenGL ES 2, shaders, OpenSL ES for audio, and upng for PNG decoding, according to the project README. This is a native-oriented stack rather than a game built around a large general-purpose engine.
Android support and latest release
The README states Android 5.0 and above. At the research date, the GitHub releases page listed v1.9.2 as the latest release. Its v1.9 notes specify minimum SDK 21, corresponding to Android 5.0, and target SDK 35, corresponding to Android 15. Target SDK describes the Android version the app targets; it does not mean the app requires Android 15.

These are repository and release-metadata statements, not a guarantee that the APK runs correctly on every Android device. Hardware, manufacturer software, and OS behavior can differ, and no independent installation or compatibility test is established here. Check the current release notes before downloading because release status and compatibility details can change. View the project’s GitHub releases.
What changed in later releases
The release history indicates that the project changed substantially after early reports of gameplay issues. The v1.2 notes address speed differences across devices; v1.9.1 notes address input lag across 60, 90, and 120 FPS; and v1.9 includes rendering, pause, text, and resource fixes. These are maintainer-reported changes, not independent test results.

An Android Police article published September 23, 2024 discussed early versions and recommended v1.1 at that time after reporting speed and tap problems. That recommendation is historical: the releases page now lists v1.9.2, so the 2024 advice should not be treated as current version guidance. Read the September 2024 report.
Where to get the APK or source
Use the project’s GitHub repository for its source and the releases page for published release files. The README also documents how to build the project yourself. It gives a Windows workflow using Visual Studio Code and build.bat, and Linux/macOS instructions using Android command-line tools, a .env file, and make from the project directory. The README says the signed APK is produced at FlappyBird/app/build/outputs/apk/FlappyBird-signed.apk.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Does “open source” mean the assets are free to reuse?
The project is publicly hosted with source available, and the 2024 report describes it as open source. But public access alone does not establish a reuse license for every part of a repository. VadimBoev’s README says: “I do not claim any copyright. The rights to the game and resources belong to DotGEARS.” That statement is a material distinction: do not assume the original game or included assets are free to copy, modify, or redistribute.

Before reusing code or assets, inspect the repository’s current license and notices and verify that they cover the specific material and use you have in mind. The evidence here does not establish a formal license for the complete project or settle rights to the original game resources.
