Divers researchers are developing the Arctic seabed, and for this purpose they went to Antarctica. Developments are at the highest level, the only thing that is bad is the fact that rapidly freezes the water's surface. Penguins hanging around nothing can help our heroes, but it can help you divers. Break the colored blocks as soon as you see a diver rises to the surface, clearing his passage to the land. Do this as quickly as possible, the air in the tank is limited.
