V0.4.3
Introducing save slots!
You can now create up to four save slots, ideal for one of each difficulty type. The "Continue" and "New Game" button on the main menu has been replaced with a new "Play" button - pressing this button now brings up the save slots UI.

Existing "Legacy" saves must be played at least once to show their stats on the save slot.

Other Updates
- The game now triggers an automatic save at the end of each day to prevent progress loss in case of crashes.
- Fixed an issue that allowed the wall clock to be endlessly resold.
- Fixed an issue preventing the letter 'F' from being typed when customizing names on the computer.
- Slightly reduced email subject font size to better accommodate long airport names.
- Minor bug fixes.
