STANDBOX is a small physics playground built around a reactive ragdoll called Stanley. He's more than a limp puppet: he can try to balance, stand up after falling, and his body is modeled with a crude medical system that includes organs and injury mechanics. You can throw him, hit him, or experiment with how different forces and tools affect him - concussions, brain damage, broken bones and blood loss all change how he behaves, and heavy damage can stop him getting back up. The current build includes three maps and a handful of tools for messing around.
