Stupid Ninjas

From the makers of Stupid Zombies... Stupid Ninjas have infested the land and you are the villagers last hope to restore order and sanity. Use your Samurai sword wisely, you only have 1, 2 or 3 slashes to clear a level... fortunately, those Stupid Ninjas carry plenty of dangerous weapons to create chain reactions. Collect 3 shuriken in each level, and make sure to improve your time bonus once you figured out the correct sequence.
