Nice submission! The sound design and voice acting really sold the experience for me, and I enjoyed the easter eggs in the menu narrations.
The gameplay was a little slow in the sense that I would instinctively react to the sounds right away, but my actions were hindered by needing to wait for dialog lines to complete. Even if the slow and contemplative nature of the experience is the point, I bet there is a balance that can be found, to tighten this up without it turning into a pure action/horror game. For example, maybe travel between spots takes some time for your character to get there, or the sounds are more subtle or out in the distance at first so you’re not hearing it before grandpa does.
