My copy finally arrived earlier today and I've been playing it quite a bit since.
It's actually quite challenging, the graphics look much better in person, and the music is pretty good.
The Cheer system seems to work well, and is both useful and entertaining. It adds an interesting and unique form of socialization that I haven't seen in any other shooter. It also provides a good way to conserve bombs by acting as a sort of hyper mode. I just wish there were a way to send cheers automatically, since sending them manually can get a little distracting with everything else going on. I've been receiving a good number of cheers from other players as well, and it's nice to see the game is so active.
As for difficulty, I find myself consistently dying near the middle of stage 3, and that's on normal difficulty. The bullets are insanely fast on very hard.
I haven't encountered any crashes during gameplay so far. Though it seems like the game really dislikes being minimized/suspended for long periods of time.
It's odd that the leaderboards don't offer a friend filtering option. Hope they patch that in at some point.
I still fail to see what warranted the hardware upgrade. This seriously looks like something that belongs last-gen.
Microsoft most likely paid MOSS to make this game for the Xbone.
I would venture to say it will at least get a Steam release down the line. Maybe even a overkill release.
This game makes use of Microsoft's Azure service, so a port on anything other than the Windows 10 Store seems unlikely.
