Sure! Here's an example of a simple Flappy Bird game implemented in a single HTML file using JavaScript:
This code represents a Flappy Bird game where you control a bird by clicking or tapping the screen. The goal is to navigate through the gaps between the pipes and avoid collision. The game keeps track of your score and gets progressively harder as you progress.
Please note that this is a simple implementation and can be further enhanced with additional features, improvements, and optimizations.
