Real Inverse today is pleased to announce the release of Paper Ninja 1.5 for iPhone, iPad and iPod touch. Paper Ninja is a fast and exciting game that requires players to make split-second strategic decisions and execute quick combo attacks. Engage the Blizzard Ninjas in the most challenging mission yet. Paper Ninja is designed so that players can feel the thrill of a sword-fight by using a finger. Just like sword fighting, it is easy to pickup but difficult to master.
