I deployed an experimental pair of PRs to the website and the online playing area:
When playing online as a logged-in user, your saved games and track designs are now stored in your user profile so you can continue playing a game across sessions.
In addition, all your savegames and track designs are also offered for download below the play area so you can use them offline. This also applies for non-logged-in users.
There's a disk usage quota of 8 savegames and 20 track designs per user account, just as a precaution (I don't really expect anyone to fill up the server with them 🙂️ ).
Please write here if you encounter any problems with the new feature.
Happy gaming 🙂️
