Just an orbital simulator to watch and enjoy! On high speeds, the figures might catapult themselves to the edge but don't worry they will come back! Paint is really best with only 1 figure, more than one clogs things up. Press E in paint mode to erase all. My favorite themes are all the paints but I also really like large rainbow. Snow, leaves, and lanterns are all really nice if you want something relaxing. When in duck mode, you are basically playing a really goofy version of duck-duck-goose. Click on ducks until a goose appears, then click the goose before it disappears to get duck points!
