Hi everyone!

Thanks for the initial feedback! I added a few things to fix some bugs and balance things a little, base don discussions we had on Discord. Here are the update notes:

- Added a "Quality" toggle for those who are having performance issues

- Added a "Quit" button

- Added some bubbly-ness to the UI

Balance Changes:

- 5$ Bomber ships now are slightly slower and have less health

- Cannons have lots more health
