That's quite the apocalyptic scene you made there. I managed to clean the sign (+++) but did not manage to get anything done on the shed (--). No matter what I tried, the circles moved way too fast and neither clicking them nor repeating after them would make any progress. If the idea is to have the player follow the circle the entire time then that part is way too difficult.
Managed to get a bit done on the next building and the car, but also there the speed is insane. It's actually so fast that the animation of the broom can not keep up with the clicking :P
I liked the atmosphere and the music behind it :)
