Voider

Voider is a twitch based action game where you need to collect the black voids which score points and then return to the middle to give time back to the counter. Score as many points as possible before the timer runs out and don't touch the four columns as you move around. NOTE: version 1.3.0.0 has a number of refinements and was redesigned to better support touch pads and touch screens dynamically. Be sure to look for it on your favorite mobile app store as well!
