This is such an impressive demo! Despite the ending being anti-climactic, it still does exactly what a demo is supposed to do: give you a sense of the game and leave you wanting for more. The concept of the protagonist's reality changing via an arcade game isn't new. There's another similar game I featured on my channel that I downloaded hereon Itch.io, but Janitor Bleeds is different because the story heavily relies on that concept.
I love how the game completely changed its tone from mysterious to scary after playing the arcade the first time. The effective use of music heightened the suspense and thrill all throughout the game.
I wishlisted this on Steam, and can't wait for the full release! Excellent job, Korpus!
