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. If one of the gauges reaches it's maximum, the machine will eventually blow up!
