Be Warned!

The games design is neat but soon you will realize that every time you will achieve a higher level (which you spent money and time for!), a new higher level will be created by MZ corporation and what you reached so far will be rendered ineffectively. This way, you might be tempted to spend more and more money (and time) with this game. How much money you will spend is the only way to keep up with the game and it will make MZ happy, but unless you invest massive cash, it will just leave with endless frustration. I strongly recommend to stay away from this game!
