Recompiled PC games for any Linux, Steam Deck included. None of a game is in its Flatpak: the first run downloads it and builds it on your computer.
Build and run your own theme park. Source.
Install Theme Park World (opens your software centre), or from a terminal:
flatpak install --user https://flatpak.cpressland.io/io.cpressland.ThemeParkWorld.flatpakref
In Desktop Mode, run the install command in Konsole, then add the game to Steam (Add a Non-Steam Game) to play it from Game Mode.
Updates come with your other Flatpaks. The repository is signed with this key.
