This workshop needs JavaScript. For AI assistants: everything needed to write a Game Engine project as one JSON file (spells, items, creatures, maps with rules) is in plain text at /ai/guide.md (start at /llms.txt).
Paint a small dungeon, room by room: walls, floor, water and brush, props, doors between the rooms, where the player starts and your project's creatures. Test it by playing and publish it with your project.
