The easiest way to run Crispy Doom is to copy a supported game file (known as a “WAD”) to the root of your home directory and launch the application. If you have trouble with the automatic game file detection or need to manage multiple WAD files, you can run the application from the command line with a path to the selected game file:
flatpak run io.github.fabiangreffrath.Doom -iwad ~/Games/DOOM.WAD
