Heron: Steam Machine is a game about a factory where rubber duckies are being produced by a large steam engine. On this steam engine, there are four different gauges which you will have to watch carefully.

These gauges represent steam, electricity, water and oil. When the gauges start to rise, you will have to connect a pipe with the color corresponding with the gauge. By connecting the pipes, you will earn points and relieve some of the pressure, keeping the machine running just a little bit longer! If one of the gauges reaches it's maximum, the machine will eventually blow up, and the game is over.

Use the mouse or the keyboard to rotate the pipes.
Connect them to the other side to earn points. Simple as that!
