One of the best games on my iPad except...

I love this game, I play it for at least 2 hours a day. I would give it a 4.5 stars instead because once you get to about level 30, you cannot get iron anymore in the mine since it is filled with other materials...this affects gameplay severely because you need iron to make tools and hire workers. Please fix this issue by making iron more available when the mine game first stars THEN adding in the other metals like gold coal silver etc. thanks
