They need to fix the bugs but good game – Farm Frenzy: Viking Heroes (Free) Review

I too am havering trouble with upgrading buildings but I think I figured it out I thought u just needed enough money to buy the upgrade but it think u need the (product + $) to upgrade I was trying with just money an it wasn't working I will have to go back to previous levels I didn't even get silver on and test it out. I am currently stuck in World: ginungagap Level: 29 Because it asked u to creat steel bars but doesn't give u the option to build a refinery to make them or a market cart to go buy ore I took a screen shot for developers if they want to ask me for it if they even read these reviews I don't know how else to get in touch with them. I hope this works. This is the first and hopefully last game from alware ill have any problems with.
