Version 1.4.9 is a technical update to "Papers, Please" that transitions the underlying engine from Haxe/OpenFL to Haxe/Unity. This is a major change that will hopefully fix a number of systemic issues that have been building up over the years on modern OSes and hardware.

In addition to the engine change, some small logic, localization, graphic, sound, etc issues have been fixed. If you see something that looks broken, please report it in the comments or through https://3909.zendesk.com/hc/en-us/requests/new

There is no new game content in this update.

A brief changelist:

• Engine converted to use Unity
  
• Many small bug fixes
  
• Added Korean, Turkish, and Czech localizations

If you run into problems and I'm not quick enough to fix them, the previous build will remain available on the legacy-64 Legacy 64-bit build (1.2.76) branch.
