oh thanks. It's just the default window is so small that I never see the icon on the bottom left window in the first place. Now it works fine.
Thanks, but F11 doesn't work. I think the developer should put a toggle full screen Option in the game menu.
Thanks for replying, I tried those keys, yet it's not working...
When I open the game, the window is extremly small. Is there an option to make the game full screen?
Thanks for sharing, I just want to mention that the bitmask actually works in 3x3(mininal), not 3x3
