Galaxy Attack: Alien Shooting is a SHUMP with a vertical view that challenges you to get rid of infinite mobs of enemies while you try your best to avoid obstacles and dodge projectiles.
This is an old-school game that pays tribute to classics in its genre like Galaga and Galaxian. The controls of the game have been adapted for touchscreens so your ship will follow the path that you trace with your finger.
Your missions are short-lived but require you to destroy a pretty considerable number of enemies. Sometimes, you'll have to face special challenges like flying through a field of asteroids or battle against the big bosses that have longer life sources.
Galaxy Attack: Alien Shooting is a simple but really entertaining shoot'em up that includes short rounds and some added bonuses such as a multiplayer mode that can be used to complete scenarios in pairs or an endless mode where you have to last as long as you can.
