Play Wrath

Don't play Wrath if you don't like to play games where there is no end. I killed over a thousand of the stickmen and nothing happened. I'll say this though, it's kind of fun to splatter their little bodies all over the ground using your lightning bolts. You can also use the earthquake ability to shake the ground and kill entire screens of the little bastards. Hit clusters of the stickmen to see a shower of blood and body parts.
