I found a bug, If I change the resolution to 1920x1080 but do NOT enter fullscreen mode, the game will not load, it loads but you cannot see it (you can tell this because the sounds all continue, you can hear yourself attack, etc.)
If I then close the game and re-open it, the screen is fully white, and you cannot navigate to the options menu to fix the resolution, I'm fairly certain that like when you tried to load the game earlier, the menu is still there, just not displayed, deleting the options.ini at \AppData\Local\GotFL fixes this issue, but trying to set the resolution to 1920x1080 again will still cause the problem again.
Here is what the options.ini looks like when broken.
[options]
resDropdownOp="0.000000"
advShadows="1.000000"
showFPS="0.000000"
gameHeight="1080.000000"
gameWidth="1920.000000"
vsync="0.000000"
fullscreen="0.000000"
musVol="1.000000"
soundVol="1.000000"

Hope this helps!
