Do you remember the classic game Galaga? This isn't exactly the same as the original, but it is a modernized version based on the classic game, designed for everyone to enjoy. Unlike the old days, you can use three types of weapons and upgrade them. Space bugs have taken over several planets. You must control a spaceship to drive out the bugs and liberate the planets. Overcome the bosses and obstacles waiting on each planet. Controls are easy. Touch and move the screen, and the spaceship will follow. When you release your finger, the spaceship transforms and changes its weapon. Upgrade your weapons with the rewards you receive every time you clear a stage. Shall we get started?
