Summary: This is a great game in concept but it is not balanced for casual, or even not so casual, players. To succeed you need to be either very good, very fast, or very very patient while you practice to improve your skills. Actually you need a bit - or maybe a lot - of each. On the easiest level the battles start out fine and are quite fun. But even though it is set to easy, the opponent is slightly faster and apparently more skilled. Eventually you get overwhelmed.
