So project 1 was new arg. i would assume the scratch cat in the project and the reverse 'costume' imply that the scratch cat may actually be a costume for the anomaly IT. As for the reason of the scratch cat having no eyes, i think the reason for that is that IT's disguise is breaking. For project two, we get two new audio clips, saying "IT." and what is either "please wait" or "never real". which can either imply 1. someone wants IT to wait, or 2. IT was never real. For project 3, we get more audio, saying 계속해서 더 빠르고 더 빠르고 더 . which in english says "IT keeps getting faster and faster and faster.", which kind of explains itself. My theory though is that these might all be hallucinations of the protagonist. WIP.
