Bug Fixes and High Score - v0.1.1

This is just a small update that makes the game slightly more playable. Behind the scenes, we have done a lot of work towards making it easier for us to code in new levels and camera transitions, so more significant content updates will be coming soon. This build brings:

• Several bug fixes. The game will no longer generate impossible wall patterns, or completely stop making walls altogether.
• The general 'flow' of Level 1 has been tweaked, making it feel much smoother to play.
• Added high score tracking.
