This level speaks for itself, though I will mention that it's rather challenging. Not impossible, just difficult. It starts out as a sort of puzzle.

There are sharks that are doing drugs. That's not good! Sharks shouldn't be doing drugs! Stop them. Be the SHARK NARC.

Arrow keys move around, spacebar shoots. Some sharks will occasionally light it up, and if you see one doing it shoot them. If you shoot an innocent, YOU LOSE!

Be the best. Be the hero. Be SHARK NARC.

How do you kill a Circus? The second-greatest trainwrecks version of a lame joke ever!
