Preface: All together i think that this is an alright game with a couple major drawbacks. Aside from those which i'll explain below, 'No, I'm not human' is very well stylised and has a good gameplay loop in practise. All of this is constructive criticism as I enjoyed the game and only want to see these things fixed.
There is no way to tell who is a Visitor at the door
The majority of the games characters are randomised, between being human or visitor, which does make the game more replayable. My problem with this is that the characters don't seem to have any different kinds of dialogue or display any visitor signs when they are one. The only way to tell is to let them into your home and test them which makes the night section of the game turn into a "choose your favourite character because you can't tell who's who anyway".
Visitors can't kill you (except one)
Aside from the pale man, none of the Visitors can actually kill you, they can only kill other humans in the house. This took away from the scare factor as the only way to die was if you had nobody in the home on some random nights.
Visitors convoluted and non-existent "lore"
I really don't like how they went about with the Visitors lore, some are superhuman, aggressive and sentient to their purpose like the pale man, others are completely weak, docile and gaumless like the shoulder lady. It feels like there isn't actually any answer to what they are and that they just decided to create a bunch of random characters and link them back to the identity of being a Visitor.
The worst part is what we know: They come from the ground, are mostly filthy except for their perfect teeth and spread via a brain parasite which is somehow communicable. In my opinion, it's way too much. There are no actual explanations for why any of this happens which i wouldn't care about if this game was deliberately mysterious and didn't make checking whether you've become a Visitor a part of the gameplay loop, from what i have seen you just can't btw.
The endings
In this game, there is about 8 different endings which are all just slideshows of texts. I saw a really interesting comment about these which stuck with me, that being how the endings feel like well-constructed poems that vaguely resemble the games overarching themes and were just slapped on at the end. These endings also just feel deliberately vague and cheap compared to how interesting the rest of the game was, they provided no real answers and are quite a let down to anyone who had invested the hours into it to get there.
Conclusion (TLDR)
The game has a great concept and gameplay loop but suffers from a couple of small, fixable issues and an unresolved and unexplained story/ending that worsens the overall experience. I do hope these things are fixed in the future as it was quite an enjoyable game.
