Steer your ship around, trying to slip by enemies (?buzzing?) without actually hitting them.
The game takes some practice, and as you gain points and level up in the Achievements page you?ll get much higher scores.
Personally, I?ve found that a roughly figure-8 flight pattern, after corralling the swarm into a manageable size, works well. I imagine there are some other good strategies as well though! Constructive criticism is welcome. :)
