Whilst not strictly steampunk it does look kind of fun! It's for wiiware, but I don't have any points at the moment. Has anyone played it yet?

"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.

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.

In Multiplayer, you are able to cooperate with friends in maintaining the steam machine. When you play with two, three or four players, the screen is divided into sections with different background colors. Each player is able to solve his or her own part of the puzzle. Players are restricted to their own section of the screen, so you will have to work together to make the pipes fit properly!"
