Ok, this has been annoying me for days now... How in the world do you get the gold star for endurance? I've gotten over 300 levels in, destroyed all objects and didn't sell, but I still do not get the gold star. Is there something I'm doing wrong?? Thanks for the help!
That's all you need to do, just destroy all the rocks and trees etc... and make sure not to sell any of your towers. The only thing I can think of is that maybe there's a rock somewhere that you missed by accident.
