Thank you so much! Really appreciate the feedback and am glad you enjoyed it!
The Metafab was used to handle player login and saving data in the "Almanac". (Which fits the "Player creation, management and saving" example from the Jam page).
Aside from that, when you beat a boss, an item gets minted to your wallet (which you can also see in the almanac).
You can go to the game page where we put more information about it!
Hope this cleared it up for you. And thank you so much again! :)
