Slow and frustrating.
While the graphics are nice and there is some degree of customization with regards to the amount of moves there are several problems that I can see with the game.
The main problem is that enemies are not affected by your combos, meaning that they can attack half way through it and usually do. The amount of exp required to unlock new combos is tedious to acquire and requires grinding. Something that while expected in an RPG is not expected in an action game. I know that this is intentional so that people without the patience will just buy the upgrades using MochiCoins. However the fact that it takes five combos to take down a normal enemy coupled with the fact that you constantly have to wait for them to get back up and then they barely give any exp is just ridiculous. The fat boss is too difficult even on easy due to the constant mobs spawning, and the fact that one hit takes away almost half of your life-points.
