Ninja Dude vs Zombies alternatives and competitors

This endless boredom buster is the unique blend of upside-down 'Timberman' and 'Ork Attack' (1984, ZX Spectrum) pushing your reaction time to the limit. A brave ninja is trapped on a tower surrounded by hordes of bloody zombies. His only chance of surviving this zombie invasion is with the help of his thick-and-thin shurikens.
