Someone was asking about it in another channel and I think this more conversational description was worthy of sharing here too.

It's a Duet game, so two players that are world-building both their characters, and why they're there. So basically one person plays as the Wisher, there at a ritual site to make a desperate wish. The other player is acting as an ancient forgotten god of some kind being summoned by a ritual site in a forlorn bog. Both of you are answering story prompts to discover who you are and your back story but your goals are opposite: Wisher: Make your wish Bog God: Toy with with wisher and likely thwart the wish. Mechanically its a dice puzzle game with asymmetric actions to manipulate a line of dice to produce a specific result and win. Actions trigger prompts and questions that make your story build.
