Hey, I really like the work you're putting in here. While this is a little rough and un-polished, the basic premis is solid and you could easily flesh it out into a nice casual empire builder esque thing for people to play on their phones. interface is easy to use, I like it. keep it up.
ps, perhapse you could getting the right icons into like a littel mini puzzle game down below to effect whats going on in the real game above.
