Version 0.3.1

Version 0.3.1

Small update to fix a bug and small adjustments.

Changes in this version:

• Made the game over condition less strict. A ball can pass the line for a very short time before it's counted as a game over. Should allow for a merge to happen before a game over is triggered.
• Added a "share on Xwitter" button to the game over screen.
• Fixed a bug. The "Best Score" number was not refreshing on the top left corner box. It was only a visual glitch as the score was saved fine in the savefile.
