Welcome to Key Gunner 1.2!

First off, thanks to everyone who donated to the California Fire Relief Bundle! It was exciting to see how much was raised, and I'm sure it's made a big impact already.

Well, on to the changelog!

• Added option to change the window size between medium (default), large, and full screen
• Added much more strict logic to prevent duplicate letters between enemies (this was my #1 pet peeve before!)
• Added more logic to avoid enemies clumping together. This wasn't usually a big deal, but it was possible for them to fully overlap each other

Please enjoy, and as always, let me know if you have any feedback!
