After an hour of playing, I am more than equipped to give my thoughts about this game.
+Variety of characters (plus 2 more if you buy the Lilith DLC. Lilith DLC includes Hilda.)
++Really nice music
+Awesome anime girls (moe and panty shots included)
--Insane learning curve
-Semi-difficult with keyboard alone
+/-Almost all characters share the same combo/Special Move inputs (this could be good/bad depending on your view)
[[ IF YOU PLAY KEYBOARD STYLE LIKE ME, DISABLE THE GAME CONTROLER OPTION VIA GAME MENU AND REBIND KEYS BEFORE DOING ANYTHING ]]
As I'm used to these types of fighting games I mostly saw BlazeBlue in this and thought it was pretty similar. I was right. Technically all 2D fighters are the same, but that's another discussion. For the most part I love it. The anime characters are interesting, but with the amount of anime nowadays, you could probably say they remind you of other series/characters--whether in games or another.
Jumping straight into the Arcade mode is a very big NO. I got my *** kicked so bad and won the first match by button mashing. The second fight was impossible. Not because it was difficult, it's because I didn't know how to play it. By luck I got back to the menu screen and did a complete overhaul of the keybindings through trial and error. I find it works best if you use ASD for Light, Mid, and Heavy attacks respectively. W for Parry, and Q for support. And the Directional Arrows for movement. This works best for me. After 5min of Arcade sessions for practice you can easily learn many of the combos. I learned all the combos for all the fighters so I know how to challenge them with whichever character I choose to play as. (Versus may not have an AI, but it's perfect for learning how to play the game.)
However, the Story mode is still relentless. The difficulty, even knowing how to form combos, was still a little high. The first few matches were easy, but difficulty continues to rise. I haven't beat it yet but I'm sure I will if I sit and focus. Animation wise there's lots of motion. LOTS of motion. Lots of bouncing for each character showing off their assets. Overall it is smooth and seems to flow pretty nicely. The only downside is that you can sometimes see the tiny white pixels around the fighters. They're even noticable in the Character Select screen. This is a small detail I can look over.
As for the Support they added into the game. I honestly don't use them. Only rarely do I do or find them useful. The music on the other hand, now that's something to get into. Just about every track--except for maybe three--I really loved causing my foot to tap while I'm laying down combos. (The Shrine music is my favorite.)
At this point this is all I really have to say. Hopefully, if you read this, will help those that play Keyboard style. I like Game Controllers as well, but PC games MUST be played using the keyboard. At least for me anyways. It adds a difficulty that many people hate, but is oh so satisfying when you show your stuff.
