Ichigeki Sacchu Hoi Hoi San (The Best)

A popular title in Japan that sees a maid robot charging around peoples houses using an array of increasingly bizarre weaponry to rd the house of vermin and the like. The sound effects are fun, if a little unhinged as the robot giggles having squashed a roach. But the overall package is a combination of the super sweet graphics and the macabre insect deaths that works a treat.
