Hey,the game still seems to be broken, ill come back to rate in a day or two just in case its a server issue, but just letting you know.
This is enabled. I suspect because it is an experimental feature it doesn't always work. Someone mentioned when they used the randomiser to get to the game it didn't work but directly going to the page did.
Is it still failing to load for you? https://skeffles.itch.io/wizard-retreat
