Loved the duotone space, really reminded me of Obra Dinn. Alien eyes were, I think, intentionally eldritch. Reminiscent of Lovecraft's Polaris where:
"the Pole Star, evil and monstrous, leers down from the black vault, winking hideously like an insane watching eye"
I didn't see all notes, but the anxiety of being watched but being unable to identify who the watcher was was conveyed. The setting of classrooms and the janitor aspect I saw as contributing to this feeling that we are an almost spectral presence meant to be unheard/unseen but yet we are clearly being seen and we are unwanted despite setting everything right again. (Just the vibes I got.) Great work.
