Oh that's weird! I don't have google analytics in the game, that's probably just an itch.io thing. I'll check out my code again later today. Thanks for the debugging help!
This is related to data corruption because Phaser isn't able to load that json from my game server. I took out the part of the code that would cause this error, so im super confused. I'll double check my code when I get home, in the meantime you can try playing on the website at https://queensbrothel.com/
Okay, I think something is corrupting your save files.
(Assuming you're using chrome)
Go to the game and press F12 to open up the console. Click the "Application" tab. On the left open up the "Local Storage" menu. Look for some jumbled url, click that. Can you delete "saveFile1", "saveFile2", "saveFile3" and then see if the game works? It should automatically create new save files when you boot up.
