Hard way

Yay, canabalt madness! But with ninjas! And a spear! And you get different targets! Which all react differently! And you have to judge when to throw the spear at them! And the gfx are beautiful! And it's got tons of smooth parallax scrolling! And the music's a looped sample! And the game's really responsive to your input! And once you begin you don't stop playing! And I'm stopping this right now so I can go back and play MOAR!
