Build a native mobile game that replicates the core mechanics of Flappy Bird. The game should include the following features: 1. **Game Canvas:** A side-scrolling game view. 2. **Player Character (Bird):** * A bird character is present on the screen. * Tapping the screen makes the bird "flap" upwards with a small burst of momentum. * Gravity constantly pulls the bird downwards. 3. **Obstacles (Pipes):** * Pairs of pipes (one from the top, one from the bottom) continuously scroll from the right side of the screen to the left. * Each pair of pipes has a fixed vertical gap between them for the bird to fly through. The vertical position of this gap should be randomized for each new pair of pipes. 4. **Scoring:** * The player's score starts at 0. * The score increases by one for each pair of pipes the bird successfully passes through. * The current score should be clearly visible on the screen during gameplay. 5. **Game Over Condition:** * The game ends if the bird collides with any pipe or touches the ground. * When the game ends, display a "Game Over" screen that shows the final score and a "Restart" button. 6. **Game Flow:** * The game starts on a simple screen with a "Play" button. * Pressing "Play" starts the game. * After a game over, pressing "Restart" should immediately start a new game.
