It is very close to the "End Turn" button thereby raising the possibility that someone will press the wrong one and terminate their game by mistake. Could the button be moved to a corner by itself, or could a message "Do you really want to quit?" come up every time the button is selected?

Maybe the "Quit" button could be placed in the collapsable button row with the settings and so on.

Quit button really needs to be there. I've separated it from the rest of the gameplay buttons, exactly to make it harder to press it instead the end turn one.

I might add a confirmation popup at some point in the future.
