The demo showcases the combat, which I still really enjoy. Plus, you get a bonus in the real game for completing the demo. UP TO 10 TIMES! That's crazy (crazy cool), and I want more demos to do things like that.
Skipping all the talking is a chore. The start button will skip a small section, but you still end up having to mash it to get through it all. This isn't a problem the first time through, but it sucks after the second time.
The game tells you the enemies get harder if you go through again, but it does so each time you go through, which I didn't know. The enemies were actually a threat during my 9th and 10th cycle.
I'm really looking forward to the full version, since I loved the first game. I didn't get a review code, so I'll have to buy it at some point. This kind of works out, since I prefer to have any Nintendo software in physical format (their digital system sucks).
