Imagine a rage game where your only input is Alt+F4. Now imagine during certain times it doesn't close the game. That's Walt F4!!

You play as Walt and you need to Alt+F4 out of popups. If your system gets overrun with these pesky programs, the game will overload and shut off. The only input is Alt+F4. This is an idea I had proving that you can consume Alt+F4 in your games, and I want to push it further. Let me know what you think.
