A free app for iPhone, by Hung Nguyen Van.
This game is a combination of a platformer and an RPG, where you can interact with the environment in order to collect gold and other valuable resources. This game is based on the legend of Arashi, a legendary ninja who fights his way through the corrupted world to save his kidnapped son from the hand of the devil Orochi. With superior acrobatic and deadly weapons, he is ready to face menacing traps and enemies who have sworn to protect Orochi.
You can upgrade your abilities using gold and diamond collected from enemies and the environment. With each upgrade, you can face challenges that are more difficult, but with your new abilities, you can overcome these challenges.
