Rocking music, although it gets repetitive sometimes. The controls are great. And the mechanics are solid.
The only problem is that this isn't a free game. It'a a demo. I think after about 7 mins of gameplay, or once you reach the point that you have to go to Bain. You have to buy the full game to continue. I have no problem with that. That's why I played this demo to completion.
But other people might have a problem with that.
Or if you really love this game, you can visit locations and level up. But as soo as you get to Bain. All that work will be for nothing.
But as a demo it's worth a try. And you can play it underground.
