I like the premise. When that night music pops on you definitely feel your heart rate go up. Those little ones on the ground gave me a good scare!
I didn't get very deep into the story so I can't really comment on that. The grounds felt interesting and it's the kind of setting that I'd love to pick up lots of little things that slowly reveal the lore. Letters, recordings, etc.
I was able to use the furniture pile to get up on the outhouse, and then up on top of the roof. So it quickly became a shooting gallery.
While I was running around I found the sprint stamina a bit confusing. It seems like its a recharging resource. Some sort of indicator of where I'm at in that would have been helpful in knowing how much sprint I had. Like an audio cue or the like.
Watching the sun set/rise from the roof was really pretty and fun to watch :D
Awesome job!
