There seems to be an issue with the game settings not saving such as you set it to no music and on start music is there again. You set it to start in window mode, and next time you load the game it starts in full screen again.
Another problem is the button for Full screen is not updating when you click it. The game starts off full screen every time, and the button to switch to window mode also says “Switch to full screen” everytime…Even when you click it it will not change the wording.
