This video shows off some areas with Guardians and their variants. I found the regular mini guardians on the plateau to be rather weak but these versions are quite nasty. They also have fantastic animation too.
The Shrine appears to be an updated version of one shown off at E3 where the regular mini guardians are replaced with these stronger variants.
I'm quite fond of how the NPCs facial animations work. Thanks to the 2D effect of the artstyle drawing an expression is much more simple than animating it normally. But the result is a game with both visually interesting camera angles for dialogue and reactive NPCs that feel believable in body language and consequently might be some of the best NPCs in a game of this type to date. Nintendo has truly mastered the art of body language in gaming.
