There is not much time spent on finding out what to do in this game: the player simply has to behave like a tough barbarian, destroying everything which can possibly destroyed.
The game offers some little puzzles, but they can be solved quite easily. There is hardly anything like a plot -- so the story is about doing what the title of the game is, and there is not much more to be done. Just kill everything. And if there is not any such a thing, try to find it. And then kill it.
It sounds dumb and it probably is, but in a funny way. The ending highlights the joke behind it all. As the puzzles are quite easy, this game is recommendable for beginners of the genre. It is short, straight to the point and positively worth a try.
