Ninja Combat (1990) game longplay

Ninja Combat is an arcade action game released by SNK in 1990. The plot is that the American ninja Joe and the Japanese ninja Ryu join forces to fight against the "Shadow Family". After defeating the bosses in the game, they will join and go to the Ninja Tower in New York City. Together, the last few defeated Shadow Family. Destroyed the Ninja Tower.
I really can't complain about the sense of operation and impact of this game. The way of moving and jumping is very uncomfortable, and after being concentrated by the enemy, there is no invincible time and you may be beaten all the time. Similarly, masters can also fight infinitely until the boss dies. Joe's shuriken is as ghostly as a Contra shotgun.
The last boss made me unable to attack anymore. Two fists and two direction spike attacks plus a little monster that was floating around and couldn't be hit. . This game is not recommended at all.
