Wow, nice trailer!
I've got no iOS device so I can't play it, but what I can say from the trailer and the screenshots from Facebook:
The cracks look amazing, the level buttons, especially the first one's with grass look great and it seems to work really well.
It also appears to me, that the sizes of objects like walls do not seem to fit to the sizes of the tanks or grass. They don't fit 100% together in my point of view.
The logo looks a bit like the newgrounds logo, but I'm stunned about the level of detail of the curb chain!

Nice job!
