Writing's on point, very verbose but in a good way. Really gets across the feeling of being thrown into a situation that you can't even comprehend at first [also, I died within the first minute because I picked the wrong dialogue choices]. One part of the character creation is a short vignette that's a flashback of your character's past life, presented as a choose-your-own-adventure storybook. You get a different one depending on choices that you made up to that point. It was very well written and pulled me in to the point where I actually seriously considered each choice I made, even though it was just a memory fragment.
The early locations are delightfully weird and otherworldly, a strange mashup of magic and science so advanced that it might as well be magic. It's got a little of detail and uniqueness that Pillars of Eternity really only had in flashes.
Combat's a little stiff right now [which will get fixed], but they're using some interesting concepts here, like having pools of different abilities [Might, Speed, and...Intelligence?] that you can expend during combat to perform different actions and using more of those points increases the likelihood of the action being successful.
It's beta, so it's obviously rough in parts, but the really important things [writing, art style, and atmosphere] are really nailed down [at least in the opening portion of the game].
