Astro Hammer is a simple old-school shooter in the style of 80s classics such as Astro Blaster, Galaxians and Space Invaders. Obliterate increasing waves of enemies as they descend from the screen and prevent them landing on Earth. Retro-inspired from early 80s arcade games. Challenging gameplay with score-minded game mechanics. Simple "pick-up and play" controls. Smooth 60fps frame-rate. Game Center Achievements and Leaderboard. No ads or in-app purchases. Designed for quick play sessions, maybe waiting for a bus, sitting on a train etc. I hope everyone enjoys it.
