About Nebula Pop
Astronomers unexpectedly discovered an unusual nebula in space. It appeared out of nowhere and began to rapidly increase in size, and this means only one thing — the nebula is inexorably approaching. When the distance was greatly reduced, it became clear that the nebula consists of multi-colored bubbles and was given the name Nebula Pop. It was decided to destroy the nebula by shooting it with multi-colored balls from a cannon. If three or more identical balls gather nearby, they will explode into a Nebula Pop and thus you can gradually destroy the entire nebula.
