Well, it's maybe an extended version, but surely not an improved version. the only thing that has happened is the adding of more monsters, a (I believe) improvement in how fluent the game is (although not that much, if it is even there).
Apart from that, there didn't change that much. And there is one incredible annoying thing about which people have complained in the old version of this game: THE POP-UP SCREEN (the one telling you to log-in) in-between battles. and not just after a few battles, no, every F****** battle has that irritating pop-up screen.
so my conclusion is that due to a lack of improvement this is not worthy of a high score. ( am aware that I can't make anything like this myself, but if I could I would pay more attention to constructive criticism.
The gameplay is fun, the graphics look sweet, but it just feels like a money milk cow to me, even if it isn't meant to be that.
