Flappy Bird game written in Ruby with the awesome ruby2d framework.

Note: the low frame rate here is due to the GIF recording not the game itself.

• Learn more about game physics and collision detection;
• Separate game logic from graphics.

• Improve opening scene;
• Improve game over scene (add medals and best score);
• Improve bird's flight and fall animations.

PRs are welcome :-)
