If you download a SLUDGE game, the package will always contain a gamefile. It is often named gamedata or has the filename ending .slg or .dat. If the game is only distributed as a Windows installer, the gamefile can be extracted by running the installer with Wine.
Once you have located the gamefile, start the game from a terminal like this:
Without a gamefile, we start the gamefile named gamedata.slg or gamedata next to the engine. Without such a file, you choose the gamefile in a file chooser.
Possible options are --help for printing the help message, --window or --fullscreen for choosing windowed or fullscreen mode, --antialias=0 or --antialias=1 for antialiasing off or on and --language=n (where n is an integer >= 0) for language selection. Options are saved, so you don't need to specify them every time.
If you entered a wrong language number, use --language=0 to reset the language to the default setting.
While playing, you can always toggle between fullscreen and windowed mode with "Alt+Enter" or antialiasing on and off with "Alt+A".
You can also play with a game controller. With the left stick or the d-pad, you move the pointer, and A and B are the left and right mouse buttons. In the controller settings, you choose an action for each button. You open them with "Alt+C", or on the controller with the Back button, which is named Share or Create on PlayStation controllers, View on Xbox controllers and Minus on Nintendo Switch controllers.
