Interesting watch. I love how she blinks super slow in the character select screen to reflect a glacial metabolism which fits an ice character. My understanding is that she's currently missing 4 'limbs' that are to be rigged separately so maybe they're floating orbs of ice or snow or something.
In the video she's in the attack section of the character select menu and has 200 health. Not sure if that's what she'll be when released as she seems more of a defense/support character with the shield and high health pool. My understanding on why Berry Brigade was pushed back and this character was pushed forward was that she's a better counterpart to wizard and was going to be support, but that may just be speculation.
She doesn't seem bad at all and while she has a monotone color scheme in her base outfit, it does fit an icy character well and isn't that different from frozen citron (and other ice characters). I like how she leaves little trails of ice as she moves too. The icy shield looks well done theme-wise and appears easy to see through too.
Doesn't seem as exciting and unique as wizard has been, but doesn't look bad at all.
Edit: As for release date, I'm guessing August as she lacks sounds, icons, and those 4 missing limbs so won't be ready in a week unless this is a much older build and they've made a lot of progress since then. I'd love for her to come in June though.
