I was wondering with the button restriction, how do you guys quit your game? During development I have the escape key set to close the game, but since I plan on using all 8 keys (and escape isnt among them) I don't have any alternative ways to close the game other than from the main menu. This effectively means that when you play a level you can not quit, unless you lose all your lives and then return to the main menu.
At the moment I don't see an alternative, but perhaps I'm overlooking something? Any other ideas?
