May I...suggest an indicator or button color change to show that the save game button has been pressed? Just so people (mostly me) don't press it fifty times expecting a different result (...yes. I do that. I know it saves anyway, but visual indications help me realise I've saved that 'turn' and so I wouldn't press it so often if there was one.) It's probably not a particularly important feature to add but it'll certainly streamline 'my' particular experience with it.
