This would be superb, except… on MacOS I can’t find an “assets” folder. Go to Steam, right-click on the game, select Properties from the context menu.
In Properties dialog, click Browse Local Files. It opens a Finder view of the games managed by Steam; select Objects in Space.app.
Control-click, Show Package Contents to see inside the .app folder. The usual MacOS app layout, including Contents/Resources which is full of hundreds of .pngs and .txts, but nothing named info_html.
