It would have been a good game if the quality was important for the developer. Forum are filled with bug reports since the day it came out. Some people can't run the game at all, achievements are not unlockable for a lot of users, graphics / sound is broken ... nearly everything you can think of. Having bugs is inevitable but the lack of communication / support only shows that the developer cares more about creating a sequel (money) than fixing bugs (quality).
It heavily feels like this game is designed for a touch screen and that the PC port was done in a hurry as far as controls are concerned.
If I overlook all the bugs and only focus on the game I would simply say this: it`s extremely repetitive as you only do one fight after another, no "world" / "story" to discover, nothing. It's a mindless loop of fights from start to finish.
Buying it is like rolling dice, it might runs on your system if your lucky enough.
