Post-jam small bug fixes (Thank you for +150 downloads!)

A new version of the game is up! I hope to have fixed some of the bugs I found after the jam ended. It's nothing big, and it doesn't add any new features or anything, but I just wanted to say thank you to all the people that have tried out the game!

- The game should now make sure to generate AT LEAST 1 player turn. This sometimes made the final score display a ridiculous negative number, which should be fixed now as well.

- There's now a volume slider in the config menu.

- Added a new part of the tutorial that explains the turn/action bar. I hope it's easier to understand now.
