I like the idea of this one and the introductory comic-style cutscene was incredible.
As for the gameplay, I found I spent most of my time trying to avoid landing in the water. Smashing things up is all well and good, but actually getting to the exit afterward was a challenge in the first map, while getting to the city proper was also difficult in the second map.
The scoreboard is a great addition, I wasn't nearly good enough to place anywhere on it though.
