Seconding the comment about the inverted camera. I just could not get used to it, and it seems impossible to collect everything in time if you can't use the camera to help steer. The cursor not auto-hiding even in fullscreen mode didn't help with the disorientation.
Items would disappear for a few frames at times, but it didn't really impact gameplay.
Aside from these complaints, I think this is good! The items are laid out in a way that leads you along without feeling too linear, the 3D models are charming, the sparse sound design is relaxing. I'd love to come back to this if an option to invert the camera is added, as I think it's getting in the way of what should be a lovely experience.
