Something about the game just made me scared af right from the start, something about the empty house, my own footsteps and the creaky wood sounds of the house made me really uncomfortable. I think this feeling was elevated by me being an intruder in the place and seeing so many potential hiding spots haha so good job on creating such a creepy atmosphere. I wasn't sold right away about the character wanting to investigate right after hearing the answering machine message but that's okay.
I liked the idea of the manual door opening mechanic but sadly it was a bit janky, with some fixes this could be a great source of tension and scares. I like the environment even if it is slightly too big for my taste, sometimes less could be more but I get that the owner is rich and stuff. Good job on the game though! very well done!
