...The project includes sprite rendering, physics, collision detection, scrolling background, user input (tap to flap), scoring, and game-over logic, all wired together in a simple but playable form. Because the code is real and running, learners can modify gravity, speed, obstacle spacing, or visual assets to see how design decisions impact feel and difficulty. The repo often includes instructions for building and running on the simulator or device, as well as commentary on how components are structured (game loop, scene management, layering).
