Extremely Similar to Mario in a variety of ways.
First of all, The shuriken ninja is similar to fire Mario, except it doesn't bounce. It has the obvious coins, It has cherries, which are similar to dragon coins in SMW.
I has Breakable blocks and block that give items, both are in Mario. You can stomp enemies like in all the Mario platformers, And you can pick them up like in Super Mario Bros. 2. It also has the same storyline where someone's girlfriend gets captured by some evil monster.
