hi guys, i been spending alot of times to find this particular retro game that only out with nintendo game. it is come from japan i sure, as the language is japanese. the game goes like tis: player control the human, where he when to fight every stages. there is a spar when u turn to a fighter, and it have 3 spots which u can block for yourself or punch the opponent, it goes with head, stomach and legs. And i still remember, when u spar with the boss which wear a ninja outfit, u can change urself into a ninja outfit. the outfit goes differently every stages, as it seems like u gt the ninja outfit and skills from the previous boss u killed.
