This game is a pretty "simple" game. Mechanics are all simple. No combos, nothing, you got like two or three different attacks, and a variety of items to help you, be it weapons or use items.
Only thing that can be called somewhat advanced is the upgrading and that's hardly complicated, just incredibly time consuming.
This game is like diablo, and old school gameplay. Grind like a mother, and you can't do many different type of actions. It's very fun if you can get into that sort of thing though. I can't beat it... or rather, I messed up my character, and stage tendency so I can't beat it anymore. I shouldn't have made shrine of storm pure black. big mistake on my part.
There are a good number of things that annoy me though. The limited options in changing it's tendency, no pause, and button layout. Other than that, it's a fine game.
