I don't know what all you guys are talking about this game being difficult on hard but it was kinda easy for me, mission 9 & 10 were actually much simpler than mission 8 on hard, this game only frustrated me when I completed mission 8 and remembered at the end the difficulty was on medium ,_, still this is a great game just like the others and I really enjoyed it, 5/5 and favorited, keep up the good work :)
I know an easy way to get gold fast: get some achievements that give you gold bonusses, after that close the game (not internet just go to a different page ), start up the game again and get all the achievements + gold bonusses instantly as you start up, aftert that rinse and repeat, I'm gettling like 2K each time I do this now. :)
not too difficult game guys, the only lvl wich is hard is the one where you are surrounded by bases in a clock like pattern, still it is possible because I beat lvl 15 =/
Kinda easy game except for the mission where you are surrounded by enemy's in that clock-like pattern, this is just like bubble tanks but with allies and a minimap 4/5 :3
