Chan Bara

Chan Bara is an Action game, developed and published by Data East, which was released in Japan in 1985.

You play a student samurai and defend the dojo temple. One joystick controls the movement, one controls the katana. In the first level, enemies attack from two different floors. You can switch between the floors to stop the enemies on the upper floor hitting you from above. One hit and you are dead. There are several gruesome ways to die.
