Nice idea, but for me the game is not intuitive enough.
I have started to play it and sometimes I am able to build things like the generator and the hydro but I have no idea why I can't build a mine and the game does not really tells me.
If you can't build a mine, you have run out of metal. The building menu shows the resources required for each building. If the building is shown in red, you have a lack of resources, if it is blue you have not researched it yet.
