Day 6:

• A first pass has been done of the final stage in the introduction.
• Interface elements have been added.  One of them tracks the coins you collect.  The other is a countdown timer which activates when you reach the final section.
• Errors have been fixed which occurred after pressing either the Enter or Escape key.  Behaviour is now as expected.
• The death and respawn loop has been improved.  Upon death or running out of time then countdown timer resets and every time gate in the level have their default values reset.
• The Flooded Temple is now lit up and marked as the end of the level with a visual arrow effect.
