Four dogs, four seasons! Each dog runs in its own season, and has to faces obstacles from time to time. When one dog jumps, the other three jump as well, so you'll have to be quick. For each red ball that a dog jumps over, you earn points. All kinds of options are possible while jumping or moving: check the 'Controls' part below this text.
Use the spacebar to jump. Press the spacebar and then the left mouse button to make a long jump. Press the left mouse button to move a dog. Hold the left mouse button to line up the three dogs.
