Sure! Here's a simple implementation of a Flappy Bird game with a forest theme using JavaScript and HTML. Please note that this is a basic implementation and can be further enhanced.
To play the game, simply open the HTML file in a web browser, and the game will start automatically. You can control the bird's movement by pressing the Space key to make it jump. The goal is to avoid crashing into the green obstacles and increase your score by passing through the gaps between the obstacles. When the bird collides with an obstacle, the game ends, and your score is displayed.
Please note that this is a basic implementation and does not include advanced features or visual enhancements. You may further customize it by adding additional elements like pictograms or sound effects to enhance the overall gaming experience.
