I just love the game,it is amazing.the controls are simple.the gameplay is marvellous and the graphics are just so realistic and wonderful.They should make ninja arashi 2 very soon.it is really really interesting.but yeah it takes a little time to complete last levels of every chapter but still it does make it less interesting and any game like this I have played is never free.As a free game this is amazingly fun.It always makes my day.When I defeated ORACHI (the boss)it was really good feeling.
