Aw, but you have more fun thrusting them into the ground or tossing them into the air and letting gravity do the rest! The knights aren't that bad, though, the hardest part is getting to evade that first blow, and that requires some deft handiwork of swiftly moving the mouse away at the last moment. Try to go by the bottom since he starts his swinging motion from the top, thus giving you more time to evade. What's annoying are the guys with jet packs. I keep forgetting about them and they fly away before I remember to move them back into the center and let them waste their fuel.
