OMG I'm really starting to think that I am really dumb ! I wanted to close the game but I couldn't do it, so I clicked on the ESC key on my laptop and then ! The menue opened ! I was able to save my game and all !
So I hope this will be useful for anyone, or everyone knew about it and I'm just really dumb lol !
Also pardon me for my very bad english, I'm still learning !
