How it works

From an idea to a world you can play

1

Give your AI the guide

It lists every block the engine has, the rules and the mistakes to avoid. Start at llms.txt on this site.

2

Describe your game

A shooter, a dungeon run, a school lab, a platformer. Your AI writes the whole project as one JSON file.

3

Import, publish, play

The Create page checks the whole file and lists every problem, with a button that copies the list back to your AI. Then publish and play alone or with friends.

What you can build

One engine, many kinds of game

2D RPG

Top-down worlds with creatures, spells, items, quests and characters who talk, and rules that say what happens when.

Side-scroller

Platform maps, screen by screen: physics, ladders and slopes, shooting, enemies that flee or surrender, companions and rules over each screen.

Expeditions and PvPvE

Teams, a queue and a run: a bag on the ground, a stash in the refuge, weight and weapon sockets.

Educational labs

Interiors such as a laboratory, a classroom, an office and a shop, with characters who talk, quests and rewards: teach by playing.

Roguelike runs

Floors of rooms drawn at random, a boss with phases, blessings and money.

3D view (preview)

An optional 3D view of the same worlds, off by default.

The workshops

Make every piece your way

Play together

Open a world, alone or with friends

Type a published world's reference in the game's menu, or pick one from the directory. Play alone, with friends or on the game server.
