I found a bug....
I was on full screen at first of course, but after a while I switched it to window. It worked fine, but when I opened it the next time I came back to play, it was still in window screen, but it wasn't working. The game mouse was where it should be, but I could click on anything with it, because the real mouse was hidden and way below the game mouse cursor. To fix it I had to try multiple times to click on options then try and get it back on full screen. After swtching it to full screen, it worked, and when I switched it to window again, it worked. So the bug is opening the app with it already on window.
