Um, for me hard to decide how many stars I should give.
First of all I thought it would be crap. First time played - also thought so. But then I stopped for a moment and starting analysing whole game and I must say WOW. Really interesting game even if not best graphic. It makes your brain to analyse next move while fighting even if you don't see it at first sight! What could be better? Um, I think a little bit quicker lvling, because now it takes too much time to spend at game till the end so from half of game it can make player bored and make them exit from the game - what I guess you want to do :)
