If you are looking for old school style games, this one you may like it. Ninja Gaiga is an action platform game with some RPG elements. You are freely to choose stages you want to beat, and you can also skip some stages. You will find or buy some power up items to help you pass through different stages, such as skill scrolls, hearts, spirits, boots, atk scroll, and wings. This is not a grind game. It doesn't have in app purchase. Everything is based on your skill. It should coming out next week. http://www.youtube.com/watch?v=ZvNRXEsNR2c
