When you click on the buttons it should not shoot, it should do what the button does. I agree tho, the unlock/lock is confusing in the main menu, but in the game its there so you dont accidentally hit the button back to menu while playing. For now I edited the game page to be a bit more helpful on this, will fix this after voting period.
