Relic Crossing: A Hop-Across-the-Lanes Arcade Game
Hop an explorer row by row across a relic causeway, in one offline HTML file: grass banks with fallen pillars, paved roads where ore carts and wagons roll through, and canals you cross only by riding drifting logs. A cart, the water or the current ends the run; the HUD counts distance and best, and a death card offers another hop. The lanes are seeded, the view is a fixed diagonal 3D camera, and every mesh and sound is generated in code.
Bring the theme, hero and vehicles, and optionally the lane mix, difficulty, hop feel and HUD text. The Skill returns a downloadable Skill (the arcade-game project, a customize guide, headless verification) and one playable example run.
How it works
Your coding agent copies the working game and follows the customize guide: palette, hero and vehicle meshes, lanes and traffic, death margins, hop and camera, HUD, sound.
Every row is generated from the seed and its index, so any world can be replayed exactly with ?seed=.
The game is played headlessly under the sandbox policy: start, a hop, quick hops, a steer, traffic, a canal, a death, Hop again and a phone run with tap and swipe.
Frequently asked questions
Does it call a model or need a key?
No. The Skill gives your agent a working game, a customize guide and verification; the game itself makes no network calls and calls no model.
Why is the demo sandboxed?
The frame has an opaque origin and no network access, so the scene can’t read anything from this page or reach the internet.
Is the game in English only?
Yes. The page is in two languages; the game’s own text is in English.
How do I make it harder?
Raise the road weight, traffic speed or count, shorten the logs or shrink the edge margin; the customize guide lists where each lives and which checks to re-run.
Does it work on mobile?
Yes: tap hops, swipe steers, and a four-button pad appears on touch screens. Verified under touch emulation, not on real devices.
Why is there no online generation?
Building a new scene needs a model key inside the sandbox, which the backend doesn’t support yet. Run the Skill with your own agent for now.
