After playing a fair deal of this today, I'd have to say that the blog review might be a bit harsh. Of course, they've had time to tweak it for launch; but the review is not off by much.
This can be a very simple game, but I've seen several people use characters at speed and viciousness similar to Arcana Heart or Gulty Gear. There is a lack of depth in moves or techinical hits, but I think beneath the surface is potential for some pretty good tactical fighting, a la street fighter two.
As of today, I've seen half of the characters employed to such skillful extent as to get double perfects, or close to all three. This competition was viewed at the Hirose Entertainment Yard, and Club Sega just a few feet west of that building.
It'd be nice to see a sequel of this, just to see the depth increase and the character set build some more.
