The game suffers one technical problems but does seem to be worth playing, here is a fix for the main problems at hand here:

Game crashing upon launching:

Go to the local files of the game, then right click WoFF.exe, go in the property tab and check the box to allow the app to be run as administrator

No way to full screen:

Just go in the local files once again and run WoFFconfig.exe manually from there since square enix can't be bothered to make sure that the interaction they're instructing you to proceed with in order to adjust the graphics works perfectly

Honestly this is just sad, making sure that the basic functions of your program works is the very least when it comes to that sort of things, and although I have no doubt I'll enjoy the game this is something that should *NEVER* occur, especially not for a AAA production

Super awesome game. It's a collect-em-all, but also has some depth and a lot of QoL features I haven't seen before all in one place.
The only bad thing is that you can't launch it directly from steam (it will crash). You have to set the two exe files (WOFF and WOFF_config) to Windows 7 compatibility mode and launch the WOFF.exe directly.

If your having problem launching the game, go in the main game file and Run this program in compatibility mode for Windows 7. It worked for me.
