A short fantasy RPG where you return to a village whose hearthfire has gone out. Simon Willison built it with Claude Opus 5.5 and published every prompt. A GPT-6 Pro take on the same idea, Lantern Hollow, is listed separately.
How Emberwick was made
Simon Willison credits Claude Opus 5.5 in the post, page or repository where the game was shared. We copied that credit; we did not rebuild the game.
