This is a beautiful game, but sadly it has some pretty bad design problems. I think there are a lot of unintuitive choices here. The biggest problem I had were that I didn't know to light the lanterns. The character doesn't have a lighter or anything to my knowledge, so how was I supposed to know what to do there. I figured it out eventually but it took ages. This could easily have been a optional thing. Just don't put the invisible wall there. Also the key in the house section should have been highlighted more. It's very difficult to find and nearly killed my enjoyment of the atmosphere at the end.
I also ran into a bug where throwing the stones looked my camera at a weird angle and I had to restart.
Aside from these problems this is a great game. You clearly put a lot of effort in the visuals and it shows. I just would recommend doing some (or more, I don't know) playtesting next time to avoid these issues.
