Too difficult! – Galaxy Defense Plus: Classic defense game Review

I want to see more defense games on the App Store, this is a good step towards that, but it falls short. You're unable to upgrade your turrets and as the levels progress it gets insanely hard!! It's too difficult and there are no walkthroughs. If the developers would make in game purchases available to upgrade turrets etc, I'm sure they'd make money. 1 star for now, this game is not where it needs to be.
