Two words to start: Volume warning.
I was initially quite confused, as I didn't realize why the tornado was getting smaller, nor what I had to do.
After losing once, though, I was delighted to find my ears shattered by how loud the sound was, but that was quickly replaced by the visceral enjoyment of how good the controls feel. With WASD, it feels a bit fiddly, but using a controller I managed to get down to 2 buildings remaining.
My only real disappointment at that point was that it still said I barely destroyed anything :-(
