"In this fast paced ninja climbing game, your goal is to rise as high as you can while avoiding killer squirrels, angry birds, enemy ninjas, throwing stars and exploding bombs. With a simple tap you can jump from one wall to the other, knocking obstacles from the air as you do. Take down three enemies of the same kind to trigger mega-jump bonuses. Collect shields to plow through your opponents with. Just watch out for ledges and other ninjas because they will knock you off and send you to your doom!
