Describe your game.
We build it.

ZeroGraft is a fork of Godot Engine where AI generates pixel art, writes GDScript, configures physics, and builds playable scenes — all from natural language.

Gemini 3 Integration

87 native function declarations. Extended thinking for complex builds. Live token streaming. Vision-based debugging with screenshots.

SpriteMancer

25 tools for characters, animations, 6 tileset types, VFX effects, and parallax backgrounds. Complete AI pixel art pipeline.

Multi-Agent System

Architecture, Character, Level, and QA agents coordinate via orchestrator. 50+ step builds with loop detection and error recovery.

Vision Debugging

Attach screenshots. Gemini sees your viewport to diagnose positioning bugs, verify visual changes, and suggest fixes in real-time.

Pipeline

From idea to playable game

01

Describe

Type what you want in the AI Panel. "Create a platformer with enemies and parallax." Attach screenshots for context.

02

AI Plans

Gemini 3 Extended Thinking breaks your request into sub-tasks. The orchestrator assigns work to specialized agents.

03

AI Builds

SpriteMancer generates art. GDScript gets written. Physics configured. Scenes assembled. All streamed live to your editor.

04

Play

Hit play. Your game runs. Iterate with natural language. AI proposes, you approve. Ship in days, not months.
