Man, what to say about this game, this is an instant classic of RPGmaker horror, the words "masterfully crafted" come to mind, it is a truly unparalleled experience of surreal horror not tainted even once by cheap tricks, the tension builds up slowly but surely as the world devolves around us, I am surprised this is technically a "one room" game but it feels big and claustrophobic at the same time, indeed like being trapped in stacked boxes, probably like 9 of them.
There is nothing to dislike here, the characters, music, art direction and gameplay are on point but I want to bring special attention to the world building, it is very interesting without being too in the face or to dense that it becomes a chore to learn about it, the characters all eel pretty real and natural even in the face of this undefinable horror. And we even get a antagonist that is more than just evil or deranged, this madness indeed has a method, I wonder if it's defined on it's class...
Anyway, amazing job, I hope this game gets the praise it deserves from a lot of people 5/5.
