I'm very interested. I hope the developers will bring the project to release, although I know from experience that most often projects from which you expect something get "Abandoned" or turn into some kind of crap. (RIP Deviant Anomalies)
Yes, my expectations are my problems, but damn, this is a really good demo.
For anyone who does not understand what to do here, follow the prompts in the game itself, and they are here too (if these are not bugs). For example, I found out about the existence of a room that can be accessed from the roof only because someone was rolling billiard balls on the floor there (by sound) and I was poking into every crack in the house, trying to figure out where the sound came from. There are good "screamers" but, ahem, bugs are sometimes much more frightening, especially at the time of completing the task (what a cool sound).
Well, the cheat menu needs to be used actively, without it, many dialogues will either not appear at all or there will be no opportunity to complete the "quest". (somewhere to make the character dumber, somewhere smarter, etc.)
P.S. For connoisseurs: For some reason, the game brings back memories of the old anime (and novel). I watched/read it about 10-15 years ago. It's called Shiki.
