I really liked the whole audiovisual presentation - the voice mimicking sounds in the dialogue, the ambient noises, the door sounds. I also really liked the weird space-warping effects in some of the hallways, like the one with the candelabra in the middle - maybe they have something to do with changing elevation, but it looks surreal. Also the way levels change when you backtrack.
Being crushed in a crawlspace was legit unsettling. That scene was straight out of Junji Ito manga.
And I didn't even know you could do 3D environments like that in RPG Maker MZ.
By the way, what's with that VHS tape? I couldn't figure it out yet.
