Reactavoid

Reactavoid is a bullet hell score attack game where each shot can cause a chain reaction. Score as high as possible with your quad-directional shot and turn the screen into a mass of bullets. 

Each enemy hit by your bullets will also explode, firing their own bullets in all four directions. Each shot can cause a chain reaction and multiply your score, but it also can fill the screen with bullets you have to dodge.
