Yes, this game is a must get if you have a 3ds.
The control works fine with the touchscreen, well at least for me as i've heard that some people said it is a bit awkward, but don't worry, it is possible to change the control setting and the camera's speed.
The orchestrated music is pretty good (dark's pit theme P= ), sometimes i find myself humming along as the music plays.
The story is good enough, and the dialogue are fun although sometimes you can't read them due to the fast paced action.
And the multiplayer mode is definitly worth checking out, even though you'll get your a** kicked the first time you should like it, plus you win some pretty good abilities and weapons at the end of the match. So yeah you have to check that out.
It would be sad to miss this game, because it is surely the best 3ds game now.
Oh and if anyone wants to play just add me ok? I'm looking forward to play with you people.
