GAMESLASHSummer Engine
By GameSlash
Game engine with built-in AI and external-agent support for building and editing 2D and 3D games.
What it is for
Summer Engine combines a game editor with a built-in AI assistant and support for external agents. It is intended for making and modifying playable 2D and 3D projects, rather than only producing concept images.
Getting started
Use the official site to choose the current app and setup instructions. Version 0.8, released October 27, 2026, installs as a new app and lists a Starter Template with lighting, characters and props, plus Board planning for people and agents.
A practical limit
Check the features and platform requirements separately: Summer Voice currently supports Mac, with Windows forthcoming. Start with a small playable scene and inspect the agent's changes before expanding the project.
