Sky Defender (SpaghettiLord)

In this game you play as a turret shooting airplanes that will constantly drops soldier down to attack you. The goal is to survive as long as possible while getting a high score! This is a recreation of an iPod game that I usually played on my iPod around 7to 10 years ago. I cant remember the name of the game, but its basically this except with white background, black sprites, and no upgrades. Please comment if you do remember the name!
