Rhythmic Virus

Your task is to keep the nanobots alive for as long as possible so that they have enough time to gather the necessary information required for breaking the code of the virus and creating the "antidote". Be careful as nanobots could be easily destroyed if too many seeds hit them or, contrary, if they gather too much information which causes the system overload resulting in setting off the self-destruction. Use bonuses to keep them alive until the song is over and the virus transmission is stopped.
