Cinder

Particle sandbox

Cinder is a PC particle sandbox built around physics simulations. You place materials in a world and test how they react: build a house from wood, bricks and concrete, set the wood on fire, and see whether the heat melts the concrete into lava. Water can put out the fire, while acids react with materials and plants grow in dirt.

Projectiles and automation

The game includes free-body physics for making projectiles with pressure-sensitive payloads. Circuits, logic gates and automations let you build systems that respond to what happens in a simulation.
