I think you should either make it easier to get coins, or lessen how much it costs to upgrade. It takes 4 or 5 games just to get one upgrade at this point.
@SmpleHarmonic You're ideas are very good, yes, but instead of putting a goblin in front of everything, since he will usually die on the first wave anyway, if you put a mammoth turtle in the front, I could get through one, and sometimes even two waves without him even dying.
It's funny how people are always talk about how a game doesn't have enough upgrades and that it needs more. And now, people are saying this game has too many upgrades? Just because it takes a little bit of time to fully upgrade everything, doesn't mean you should get mad at the developer because of it. This is a really good game. I applaud IriySoft.
To get the hard badge, all you have to do is to pause the game and turn of the sound and the time goes slower. But then you have to compensate for the 600 seconds, which will actually be a lot longer. Rate up to keep alive!
