Playing this game was pretty relaxing, seeing as it's based around destroying structures at your own pace. I spent a while just running around turning everything to rubble, just because I had the option to. I also appreciated the fact you could turn off the camera shaking effect.
I sort of wish that the player character was a bit lower off the ground, as in the second level I felt a bit "sunken", so to speak. I also agree with the other comments, in that other things to destroy, or different ways of doing so, would have spiced up the game and added more variety.
Good work either way!
