Gearbits: Gear Angels

Gearbits: Gear Angels is a 2D side-scrolling shoot 'em up. You must defeat the invading alien fleet to save the planet! Your shield will protect you and your weapons can blow away entire squadrons of alien ships. The catch is, your energy depletes fast. You'll be in trouble if it runs out! The shield won't protect you and your attack power is reduced. But at maximum energy, you can fire powerful shots that pierce enemies and shrug off lethal hits with ease!
