could have so much potential. The gameplay itself phenomenal, yet they did that stupid mobile trope, where they give you 20 "click me" buttons that give u a small number of rewards. this makes the game turn into a chore at times and visually annoying to look at. they also don't know if they want to make the game a event game or a story game and poorly merge the two. so some players do only the story mode or only the events(which is fine I guess) but then they force u to do one to do the other.

I gotta say, this game is absolutely incredible. Especially for a mobile game. The visuals are beautiful, the music slaps, and the story/cut scenes are awesome! The game play is super fun and addicting as well. The icing on the cake was the option to switch from the English voice actors to the Japanese version. Give the game a try! You won't regret it.

This is one of my most favorite mobile games ever. The design is great, the game is very fun with steadily increasing difficulty, and there's no pay wall so far. I've gotten to Super Ninja III and am still having a great time. Also, there are no ads at all. No forced or even optional ads. You just don't see that in a free mobile game, ever. I highly recommend this game.
