Nice but...
It's nice at first I loved the updated, cartoonish cute graphics but then the game just didnt live up to itself because it just gets so repetitive and the AI is really really stupid (which is ok for earlier level). You should use this concept to construct a much larger game and leave the Battle City concept, it is too old. Try to make a game where you engage like an army and you have allies... basically like a tank battle game, it'll be much cooler.
Please please please. Don't ask us to pay to play your whole game. It feels like an insult to us.
