I'm honestly not sure why people are that pissed. Maybe it's still a rather early build. Sure, there's error and hiccups, but if the core gameplay - I haven't followed the game at all - is okay I wouldn't worry too much right now.
Some people also just shit on the game because it's on Xbox One. I mean come on, someone said those are last-gen graphics.
I don't know, but people losing their shit over some indie game that they know nothing about just because of generic-as-fuck indie art style ("Oh look, ICO!!!") is equally annoying. Okay, it's unfair to call the art style generic, but it's really nothing mindblowing or new. I mean come on, the thread title is 'If ICO and Wind Waker had a baby". Fuck that.
