The Last Ninja (Ion International)

Not to be confused with the more famous Last Ninja from System 3 Software, this is a side-scrolling platformer developed by Cleveland M. Blakemore and published as a type-in game in Ahoy! 1986/09 (Issue #33), and was in Loadstar #244. The Last Ninja puts you in the garb of a shadow assassin armed with shurikens and opposed by a string of successively stronger opponents, ranging from sword-wielding evil ninjas to fire-breathing dragons.
