Cool, but...

Very nice app, which is rather interesting, but! Now I will give you some recommendations for creating some new things( in brackets is written possible resource for game)
1)Please add such energy generator as nuclear reactor which is consist of few blocks, turbine( some cooper and bronze, electrical generator) fuel rods (uranium, iron) control rods( carbon and iron), biological protection on the sides (gravel and sand)..
2)Please make update of trade portal less expensive.
Thats enough))
