In Bombs Away, you have to shoot the exploding aliens before they can get to you. Fortunately, when one blows up, it leaves a residue that can blow up the others if they're close enough. Unfortunately, they keep coming faster and faster... and they start doing funky things like bouncing over your bombs. So it's pretty likely that they'll eventually get you. But try to stay alive as long as you can, anyway.
Controls:
Use mouse to aim and shoot. Click and hold for greater distance. Be advised that you can only shoot one bomb at a time, so aim carefully.
