So I played the demo, and I freaking hated it. Here are my complaints...

I- have no freaking idea what I'm doing. Why is'nt there a clear tutorial or indications about the controls? Is there anything I can do other than the same lame 3hit combo over and over again? Things started to be better when I used items, but other than that all I was doing is smashing the same attack button giving me the same 3hit combo again and again.
-Is there no lock on button? That thing is running around sliding everywhere like crazy, it was extremely anoying having to try to folow it.
-How many times to have to hit the thing in order for it to go down? As far as I know you can't see the monster's hp, at first I thought it was cool to not exactly know when the thing will go down. But after hitting the thing for so long w/o having any clue on when the thing will die, it started to get boring after 10min, it then went from boring to frustrating after 15min.

I'm a total newbie to this game, so maybe I'm wrong in many aspect, but this was the impression gave me, a first time player.
