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, 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 bit longer! If one of the gauges reaches it's maximum, the machine will blow up, and the game is over.
