Galaxy89 is a fast-paced multidirectional scrolling shooter where enemies close in from every direction. Steer your ship freely with the virtual pad, push forward, and blast away with rapid fire. Tear through swarming enemy formations, homing kamikaze fighters, and entrenched gun turrets. Defeat enough foes and a massive boss appears—survive its spreading shots and high-speed orbits to clear the stage. Two full stages of arcade action await. The satisfying punch of a classic arcade shoot-'em-up, distilled into a one-handed, portrait-style experience. High scores sync to Game Center leaderboards, so you can compete with players around the world. Features - Satisfying all-directional shooting controlled with one thumb - A variety of enemies: formations, chasers, turrets, and bosses - Two full stages plus tough boss battles - Game Center leaderboard support - Quick, replayable score attack for any spare moment
