Help the brave astronaut Doggy to cope with the aliens. They approached the earth's orbit and settled down, waiting for an opportune moment. To protect themselves, the alien ships have surrounded themselves with colorful bubbles and thus expect to protect themselves. To get to each plate in Bubble Space, you need to destroy the bubbles. Shoot them, bringing together three or more identical balls together. When the bubbles surrounding the alien burst, his starship will crash down. But hurry up, time is running out and when the number on the alien aircraft reaches zero, something terrible will happen in Bubble Space.
