Ninja Dog

This ninja dog has to get rid of all the fruits in the trees, but on each level, he'll have different targets. Sometimes he just needs to get rid of the ripe fruits, without touching the rest. You have to help him to set the power to throw the shuriken, when he needs some power the arrow has to be short, but when he needs a huge power the arrow has to be long. Each level will be harder!
