Galala

GALALA is an endless space shooter inspired by the golden age of arcade. Alien swarms sweep into formation, then peel off to dive at you in curved attack runs. Blast them, dodge their bombs and grab power-ups: twin cannons, a piercing laser beam and mega bombs. Every third stage a giant boss appears with its own life bar and attack patterns.

Watch out for the tractor beam: lose your ship to it, shoot the captor and you fly back out as a dual fighter.
