I actually thought it looked rather great.
As someone who hasn't played the Kiseki games beyond 15-ish mins of the Vita game that was on PS+ Japan recently, I liked what I saw.
The action gameplay looked fun, though I'm trying to wrap my head around how deep it will be. Enemies look reaallly uninspired unfortunately.
But I really like urban environments set as a setting, (or at least an overworld/hubtown in this case) so it's nice we get to see that for a change of pace.
The character designs looked rather nice too, sure the tropes can be seen from a mile away, but they still look good.
The shoe-horned idol stuff at the end looked dumb, but overall the game looks like something I'll enjoy.

Also, where have I seen that stiff walking animation before in a Vita game? I distinctly remember playing a game with really weird animations like that, was it Ragnarok?
