The characters have changed, but otherwise this game is almost identical to Timescape's Wild West Hero.
Mind you, both games are excellent versions of the arcade classic Robotron. They include the handy feature of automatic firing in whatever direction you're moving so you can concentrate on the movement.
You are granted a large number of lives, which is just as well because the action is incredibly fast. Your dustman is overwhelmed by a screenful of rapidly changing objects, ranging from wobbling joysticks to scissors to hi-fi racks, depending on what level you're on.
By obliterating certain fixed objects you can get the 'Bin-liner's Friend' to appear. Touching him takes you up a level. The objects are small but their motion is beautifully smooth. The only disappointment is that the action is basically the same at every stage.
