I found a likely cause and have published a fix.
The game creates a save after you choose your Oath but before entering the game. If Chrome blocks persistent browser storage due to a privacy setting, extension, or site-data restriction, that save could fail and prevent the game from starting.
The game will now start even when persistent storage is unavailable. If saving is blocked, you will see a warning with instructions for fixing it. You can then test saving again or continue temporarily without persistent saves.
Please try the updated version when you have a chance and let me know if you can enter the game successfully. Thank you again for helping me track this down! :)
