I liked this a lot! The visual style very much feels like your own thing, while also being reminiscent of first-wave PSX games (the way the scale in the apartment is all wonky reminded me of Lara's mansion in Tomb Raider, for example). I also enjoyed the general atmosphere, and the genre-switch in the middle was fun.
Oh, and the guy sliding out of the wall worked as a pretty effective jump-scare! You got me with that one.
