To Install, run this NSIS installer and choose wherever you want to have the game installed. Afterwards, go to that location and make a new shortcut to the game instead of the launcher. Settings are best changed with a text editor by opening the .lua files. Custom resolutions can be set in app_config_incl.lua and to fix streching - tab out to the desktop, then go back to the game.
