Hello Sean Niemann,
I can see that you are making the single player version of Runescape Classic. Everything seems to work out as a running server, but as a client alone, there are certainly things to be desired.
First off, we need to save player data upon single player account creation (data can be deleted from its directory under normal operations). We cannot go on and live with username test, zoso, and root. Next, we need to save the progress of the singleplayer account upon logout/exit. Perhaps make the beds/camp an option to save and logout/exit. Resting should be a part of the game. For instance, we cannot heal health or restore points fast enough. Resting will heal health or restore points faster. However, you are still playing the game! If you do get attacked or run into some mishap, you wake up and resume game session. If you die, you have to reload saved game session; it's more lenient with multiple saved game sessions from load slots. Maybe make the singleplayer version of Runescape Classic with permanent death (one death will delete account along with saved player data), otherwise, it doesn't sound like an achievement? Maybe too much roguelike references, but you get the gist of the request. Am not sure about how permanent death deals with the iron man modes.
I am not sure, but maybe a camera zoom feature be possible if not implemented already? I recall that orsc client increase sight radius upon increasing the program's window size dimensions. I also know that orsc's own singleplayer game is currently unavailable.
Maybe make a flatpak version of the Runescape Classic SinglePlayer game as well/
Sincerely,
