RuleBox Game Engine

Build puzzles where changing the words changes the rules.

Rulebox is a browser-based puzzle game creator inspired by Baba Is You. Design levels, create your own artwork, compose music, and export a standalone HTML game without writing code.

Place objects and word tiles to build rules that players can rearrange. Make rocks pushable, transform objects, and experiment with puzzles where the solution means changing how the world works.

Features

• Visual level editor: Paint tiles, fill rectangles, zoom, pan, and organize multiple levels.
• Rules made from words: Combine properties, transformations, and conditions to create surprising interactions.
• Built-in art tools: Create custom objects and word tiles with pixel and vector editors, including three-frame animations.
• Music Studio: Build instruments, write patterns, and arrange your own soundtrack.
• Instant playtesting: Try your puzzles without changing the original level.
• Creator checks: Inspect active rules, debug object behavior, and check projects for problems.
• Save and export: Save editable projects and export standalone HTML games to share.

Start with the tutorial or a blank project, then build your own collection of rule-bending puzzles.
