Leave yandere simulator?

Hi! I downloaded the game yandere simulator on the laptop and played. Now I want to get out of the game but I do not know how. I tried to press escape, but it does not work. I ask for help.

ALT + F4.

And maybe someone can tell me how to make the volume quieter or louder?

Thanks! Do you know how to change the volume?

The game will probably have somewhere settings / options.

Otherwise stop the volume of the laptop change.

If necessary, simply open the Volume Mixer window and turn the game down. (Click on the speaker icon in the system tray and then open Volume Mixer)

With the keys otherwise no idea there are buttons for it
