Very atmospheric. For some reason it reminded me of The Talos Principle. I was drawn in and motivated to find (I think) all the notes, and try all the endings.
I did have a bit of trouble with the controls. I grabbed an old Steam controller I had laying around, and the mappings didn't line up at all to what was in the diagram (Probably not your fault, I was surprised it worked on the web version at all, I've had trouble in the past), so I switched to keyboard and mouse, but had to kind of guess at all the controls beside "F" for interacting. They're pretty standard controls though, so that wasn't too bad.
The sparkles are helpful for finding the next goal, which was good because I did things like try to interact with the lamp oil to early, and decided "huh. That must not be the lamp oil." So I would have gotten stuck there if I hadn't seen the sparkles from outside the house.
Overall an enjoyable experience.
