Since we’re talking about ‘Exit’ Buttons, after you click it, you go the ‘Credits’ screen.
At the bottom left is a ‘Power’ icon, just above a big ‘X’.
The ‘Power’ icon is pretty intuitive. The ‘X’ is about as UNintuitive as is possible.
How about instead of an ‘X’, put ‘Cancel Exit, Return to Game’.
Wouldn’t that be about a magnitude clearer? 🙂
