You have to kill off all the bacteria within a limited number of turns. And it's relatively easy to pass the levels. It has a few really interesting dynamics that make it very, very complex. If you don't clean up all the bacteria in a turn, then they will grow exponentially and unpredictably. Also, you get a higher score if you let the bacteria grow a little before cleaning them up. So, you have to balance timing of getting rid of all the bacteria with letting them grow too much so that it's impossible to clean up. So, it's very easy to get a lot score, and very very hard to get a high score.
