version 1

Initial release features:

• Uses Phaser v1.1.4.
• solo player and two player modes.
• sounds and particle effect.

version 2

• support touch and click movement.
• better ball and paddle collision. feels like an ice cube instead of a rubber ball.
• add many code comments.
• refactored player data in separate objects allowing for homogeneous movement code.

version 3

• only bounce the ball off paddles and walls if it is approaching them. fixes a bug where the ball gets stuck between two bouncing states, like schroedinger's cat.

• fix paddle start positions to avoid a race condition where the game world size does not reflect the expected value. and adjust the walls size and positioning for a more seamless play area.
• reduce goal margins to avoid very fast balls from triggering goals on successful blocks.

• separate style sheets for desktop and mobile.
• AUTO rendering mode will choose HW acceleration if it is available
