Beautiful work there, nice graphics, solve "for me" the game problem with progression, making everything more useful, solve "in part" the stone problem from angels at start, kind like force you to build a better factory. The small electric poles with iron are very handy. The turbine is very nice too. Amazing there. That should be bind to the game core.

Would be nice if was other variant for the "Basic insulating board" that does not require wood. But that is me.
