I loved games, and in my infancy I used to be an "adult playing observer", passing hours watching people inserting 25 peseta coins for additional lifespan in Gauntlet, or trying to consume all Out Run's in-game melodies and the colorful USA-wide scroll. Defender, Space Invaders, Galaxian or Donkey Kong are the first ones I remember, full of charm, in bars, mini-golf resources, or swimming pools near León, with a delicious smell to tapas.
Galaga (ギャラガ, Gyaraga) is a fixed shooter arcade game developed and published by Namco in Japan and published by Midway in North America in 1981. It is the sequel to Galaxian, released in 1979. The gameplay of Galaga puts the player in control of a space ship which is situated on the bottom of the screen. At the beginning of each stage, the area is empty, but over time, enemy aliens fly in formation, and once all of the enemies arrive on screen, they will come down at the player's ship in formations of one or more and may either shoot it or collide with it. During the entire stage, the player may fire upon the enemies, and once all enemies are vanquished, the player moves onto the next stage.
Galaga has proven very successful. The arcade version of it has been ported to many consoles, and it has had several sequels, most recently Galaga Legions for the Xbox Live Arcade service.
The objective of Galaga is to score as many points as possible by destroying insect-like enemies. The player controls a starfighter that can move left and right along the bottom of the playfield. Enemies swarm in groups in a formation near the top of the screen, and then begin flying down toward the player, firing bombs at the fighter. The game ends when the player's last fighter is lost, either by colliding with an enemy or one of its bullets, or by being captured.
