Combustor

Game premise and objectives

Combustor is a 2D gas simulation where you manipulate gas dynamics within a grid. Each cell contains various gases with specific amounts, internal energy, and velocity. The game does not store pressure and temperature; instead, these measurements are derived from the state of the gases. Your primary actions include adding moles of gas, introducing heat, and constructing barriers to alter gas behavior.

Building and reactions

You can draw walls and place generators, but ignition requires careful arrangement of fuel and oxidizer. Combustion starts at 700 K, while ambient conditions sit at 300 K, meaning you need an ignition source and a sufficient mix of gases for combustion to sustain. Various reactions are present in the Chem Codex, each with its own requirements related to temperature, pressure, and reaction timers.
