Please say this is going to be a game.
This can make a good still piece of art but for game I doubt it. However, it's still cool.
Currently working on turning that standstill mockup into an actual game in XNA. It's hard to figure out how to render stuff the way I want, but I'm off to a pretty good start and I think I know exactly how to handle the "bubble" effect around the edges.
If it works out then I intend for it to be a game. Though I doubt I'll ever get quite the same effect as I can in a mockup, I should be able to get something close.
EDIT: here's a preview
of what I have running in XNA.
