A Flappy Bird style game in C++ and raylib. It started as a Programming 1 group compulsory at INN in 2025 (I wrote most of the code) and I kept poking at it after. This repo holds all three versions, one per branch.
Play it in the browser: sundorigin.org/play.html or on itch.io
| Branch | Version | What it looks like |
|---|---|---|
main |
v3 Neon edition (2026) | Synthwave grid, everything drawn in code, difficulty select |
2025-pixel-clouds |
The one I handed in (2025) | Pixel art city, brick towers and those big cloud ghosts that sit right in your way |
2025-skyscrapers |
Before the pixel art (2025) | Photo skyscrapers as obstacles and a real skyline in the back |
They all build off the same code. Same game states, same flight physics, same controls.

What's new compared with the 2025 version:
- Neon grid look, all drawn in code. No image files at all.
- Light trail behind the plane, derez particles when you crash, +1 popups
- Synth sound effects and two synthwave loops (one per plane), generated by a Python script
- Easy / Normal / Hard. Changes the gap, the space between towers and the speed.
- The gap can't jump further than the plane can actually climb. No more impossible towers. You're welcome.
- Time based movement, so it plays the same at 60, 120 or 144 FPS (the original moved a fixed amount per frame, oops)
- Separate high score per difficulty
- Mute button
| Key | What it does |
|---|---|
| Space | Flap (hold to climb harder) |
| X | Swap between paper plane and jet |
| 1 2 3 or Left / Right | Pick difficulty |
| P | Pause |
| M | Mute |
Windows, Visual Studio: open RayLibStarterTemplateEmpty.sln and press F5. raylib is already in lib/. The game loads sounds from resources/, so run it from the project folder (that's the default in Visual Studio) or put resources/ next to the exe when you share it. Needs raylib 5.0 or newer.
Web (Emscripten + raylib built with PLATFORM=PLATFORM_WEB):
em++ src/main.cpp -o flappy-plane-v3.js -O2 -std=c++17 -I<raylib>/src <raylib>/src/libraylib.a \
-DPLATFORM_WEB -sUSE_GLFW=3 -sASYNCIFY -sALLOW_MEMORY_GROWTH=1 -sINITIAL_MEMORY=67108864 \
-sEXIT_RUNTIME=0 --preload-file resources@resources
New sounds: python tools/make_audio.py rebuilds every sound in resources/ from code (needs numpy, and ffmpeg for the .ogg files).
