forsen pls come to Brazil

That's right, if you don't exit the game you don't need the button to exit .

just never exit the game, simple solution

If a game requires a guide on how to close it, it is probably not a well designed game. If Alt F4 breaks it, it probably would break sooner than later on something equally stupid anyway.

im doing alt+f4 and then you become the option to close it

Sí, está mal porteado a PC.

menuda basura, no sois capaces de poner un botón de "salir del juego"? vaya decepción...y encima toca sincronizar con Google cada vez que entras al juego...poneros las pilas pero ya, o lo vais a lamentar...

No, they just made a poor android port to PC

Yes and no, better safe than sorry would only apply if you were aware of the technical limitations of what you're doing.
In this case, considering all is saved server-side, and hell you even get a pop-up to ask you if you want to quit the game when you alt-f4, it's very safe to say that nothing will occur if you do so.
And considering there's even a pop up in the first place, the devs know that this is how a PC player would want to exit the game, especially if they have to click on 5 different things all accross your screen, waiting for loadings and such. So why take 10 seconds to close everything when you can literally take 1?

Better safe than sorry
