Added all the final things I think are necessary for 1.0:

• There is now an ending to the game. Huzzah!
• An "About" screen and credits.
• A functioning pause menu.

Some minor updates:

• A new font throughout. It turns out my first choice was only free for personal use, and a game/app license was going to be $400. The new font is more readable anyway.
  
• The credit counter shows green text flying up for things that add to your score, and red text flying down for things that take away (fines, purchases).
• The Carrier end-level scene now gives an itemized postmortem on your score for the level: how much your gems were worth, minus deductions, plus bonuses.
• You can now continue straight to the next contract from the Carrier end-level scene with a large "Next Contract" button.
• There is a bonus you can earn, but you don't know what it is until you earn it, and it's very difficult to get. Of course.
• Updated some level intro text.
• There are now only 24 levels.

What's left is wider beta testing, and making a video and promotional stills. Then it's to release!
