Very well done. My fave was the 2nd level.
As with many other in the Xiao Xiao series, this game is short, as to be expected from most Flash games. I did find the graphisc to be quite good. It doesn't offer a whole lot, but it's very well done, especially the physics (and the cannon bit on level 2). Sound was better than most Xiao Xiao games I've played, especially since it has a lot more content. Though the game was rather simplistic, short, and easy, it still had very entertaining victory videos (and some defeat videos that were even more entertaining, sometimes). Overall, it's very nice.
