The game Circle Run can be endless if you are very dexterous and your reaction is perfect. This rarely happens, so don't worry if you manage to score less than ten points on your first try. They are assigned after each successful passage of the obstacle. The square moves in a circle, and sharp spikes literally grow on its way. It is important to click on the shape in time so that it changes the outer path in a circle to the inner one or vice versa. It all depends on which side the spike appeared from.
