Sandbox Framework that features custom asset and graph editor for your game

Sandbox is a minimal and generic framework that lets you add sandbox features to your game.
Typical real world examples like Creative mode, map/level editors at runtime.
Includes example project that show how you switch between edit/play mode, spawn assets and save it as a playable map.
