You get the engine while it's being built. It changes every week, some things will break, and what you report decides what we fix next. The app tells you when an update is ready.
You need an AI to build with: connect Claude Code, Codex, any MCP app or your own API key (free from our side), or use the built-in AI with Sparks. You can also build everything by hand.
Your games are yours. Export them as their own app.
Beta 1: Make mode (describe your game, pictures, time of day, weather, wind, six looks), Games in Development with five sample games, 14 Quick Tools, every tool by hand in the Tools window, a bigger Node Graph, and the Vulkan renderer for games on Windows and Linux. Already have Arcwright? The app offers the update by itself. Everything in Beta 1
