Sure! Here's an example of a simple implementation of the Flappy Bird game using JavaScript, encased in script tags within a single HTML file:

Note that the full implementation of Flappy Bird game involves creating pipes, implementing collision detection, and scoring mechanisms. However, due to the limited space provided, I've shown a basic example that allows the bird to jump, fall due to gravity, and detect when it hits the top or bottom of the canvas to end the game. You can extend the implementation by completing the `createPipe()` function to generate pipes, implementing collision detection between the bird and pipes, as well as scoring when the bird successfully passes through the gaps in between pipes.

            canvasContext.fillText('Score: ' + score, 20, 25);

if (birdY + 30 > canvas.height || birdY < 0) {

            }
        }

// Create a new pipe
        function createPipe() {
          // implementation of creating pipes
        }

// Move the bird up (jump)
        function moveUp() {
            birdSpeedY = -3;
        }

// Game over
