Best on a computer

You wake beside a campfire in Hearthmoor, a meadow by a river, and head out across an open valley toward a distant spire. Fights reward well-timed dodges and parries, and waystones let you travel back along the paths you've opened. Best on a computer: it needs a keyboard and mouse.

How the creator made it

The creator had Claude Opus 5.5 build the terrain, creatures, combat animations, sound and music in code, with an AI-generated cover image. They say the project took about 16 hours and two prompts, with three interruptions at the session limit. The creator says the API cost came to about $1,440 across the agents building separate parts, the main session that put them together, and the trailer that Claude edited and scored.
