For context, I survived one full day/night cycle before quitting since I assumed that was all there was in the game.
The mechanics were odd, I don't believe I would've understood any of it if you hadn't explained beforehand, even now I still am unsure what the deliveries do. There are long stretches of time where there is no music playing and nothing to do because there are no deliveries (some of the objects fall through the ground before I can pick them up and permanently take up that spawn location). The doors that randomly open in the night couldn't be closed unless I had a delivery for that house first, which I felt was odd since that also left the night feeling mostly empty even when it was meant to be more tense. The chase sequence was interesting, though just telling me to click made me confused on which button to press, so I just started pressing every available key I knew did anything to see if it worked, and there was no indication I was making progress until I suddenly got let go a house away from the evil door. Another small thing is I think having no left and right movement does significantly detract from the experience, mostly since those are just 3D controls you always expect to be there.
I really liked the graphics, it felt like there was a good style going, though I'd like to see maybe a skybox or something blocking the edge of the world so it's not just obvious it's a plane. The audio was good as well, my main complaint is just wishing the songs looped to always be playing during the day and night instead of cutting to silence for a majority of the game. I didn't really notice the cameras doing the things you said they did, but that could've been me not doing something to trigger that behaviour on my end?
The gameplay was original, though not very enjoyable since I wasn't sure what my objective was other than vaguely "survive", and I think a tutorial (even just a small thing when you load in or in your house) could help a lot with that.
Overall, genuinely a pretty good 3D prototype that feels like it could be expanded on in a lot of ways to be a really interesting take on survival horror, can't wait to see how you end up developing it!
