Alright, first impressions after the really tough first fight:
What's really cool is that the character has three fighting formations. So instead of just switching between 3 swords, you switch between cat mode and human mode. And then when you have enough souls from killing enemies in battle, you can transform into one of two super powerful modes, where you can do MASSIVE DAMAGE and are also invincible for a short period of time. Depending on if you transform into the super mode as a cat or as a human changes which super mode you go into.
So I thought this is really neat and actually prefer this system over the sword system, just because it's like 2 characters in one. And the way you fight in both modes is similar to how you do in the main game, but this cat chick is really fast and it's really satisfying to do combos and dodge and stuff.
Also, the animations are amazing and it's awesome just to watch the shit happening. For some reason I was worried they would half ass it or something because of this being some DLC for a Vita game that came out half a year ago, but nope! I guess it took so long because they worked so hard on it lol. It's really cool, and I'd say definitely worth $5 if you want some more out of the game.
Then again, these are just me playing the game for 20 minutes, but I don't see my opinion changing
