A science experiment went terribly wrong, resulting in nanites on the loose. The nanites spread to fill all empty space. To prevent that, you must surround them with their dead. Use your Android device to remote control a powerful laser and with it to destroy the nanites. Drag your finger to scroll and to move the laser. The further away your finger is from the center of the screen, the faster is your scrolling speed in that direction. A percentage in the lower-right corner of the screen shows how much of the area you are controlling. Your job is to prevent the percentage from dropping below 30% or it’s game over. You need to stop all the nanites to advance to the next level. Nanite: a nanomachine, esp. one capable of surviving and replicating on its own.
