WAY too easy to get past your fortifications. In the tutorial, I got to level 11, bought the Catnonans (or whatever), and died. It was literally like, POOF! And there goes everything I built.
Bullshit. Not only do I start off at the low ground, but they need a line to show you WHERE THE FU-- IT'S GOING TO GO. Some people spend all day perfecting this crap and they ruin it for everyone else by perfecting it. Make it fairer. Like I said, Bullshit!
