Updated to Version 1.2 - final release

Updates:

• Added a high score tracking system
• Made the walls more visible and more of a barrier
• It is now easier to pick up arrows and they stay around longer in the world
• Arrows are now more visible in the world and in flight (increased size a bit and fixed particles to show them better)

Bug Fixes:

• Fixed arrow particle effect to look better and be more visible
• Fixed and issue where if there were several arrows in the world and none in the quiver, the game would end as soon as the first arrow in the world was destroyed
• Updated the input system to remove errors on scene end

Known Issues:

• Arrow pokes through the string when drawing it back
• The score particle reflects the scene when looking down towards the ground. Look up to see the score value more clearly
