I like what I've played. Up to about chapter 4 or 5 right now, so I've only seen a taste. Really cool though.
The thing that sticks out the most to me is something really minor. The menu design (at least the chapter select) feels really good. Would be nice to have rumble feedback too, but no big deal. I have fun just waving the pointer around on the menu like an idiot.
The flying is really fun. Feels great to just zip from point to point in this majestic little pattern. Walking around feels terrible though (I guess maybe on purpose to encourage flight?). Camera control is bad. But those are ok, because you're almost always flying.
Going in an arc everywhere seems a little weird. Can I fly quickly straight at something? If I just let go of B it seems to kinda burst that way, but not a full speed fly towards it.
Not sure what I can do the attack sometimes, and other times I can't. I don't think that was explained well, if at all.
It's a neat game, and I'm glad I picked it up. Gives a strong Nights vibe for sure.
(Playing the Wii version btw. I flipped the cover right away, swapped instruction manual order, put it on the shelf with the Wii games and I'm considering the Wii U version as the bonus. Shoutouts to NIS America for handling a Wii release in 2015 so well! They've included everything to make it a proper release for both systems. Will probably try the Wii U one soon just for comparison.)
