You guys probably noticed and enjoyed the Screens of Rage feature that display a picture of you beating every boss you found in your path. You can actually save those by heading to your savegame folder and copy the png files that have been created. Be fast though coz they are deleted after being displayed in the screens of rage. Remember that you can switch from fullscreen mode to windowed mode with Alt + Enter.
So anyway, why don't you share here your most epic Screens of Rage?
