The intro could use some work in terms of showing the story, could do with some visuals to cut some text and spice it up or show it off in another way. It just feels too much for the start but understandable why you want certain info to be shown. 

I don't know if it's the path I took but the demo is way too short and felt it more like a concept. There's not much to really see. The puzzles were too easy. I actually like the fact there isn't that much jumpscares. The game's atmosphere, along with the music and sounds, was good though! I definitely felt tense just being in the park. UI is readable and pretty nice overall. The notes were nice though it seems too early to be seen especially the grave. The newspaper and the chess game looked too new and undisturbed.

One thing that bugs me was the phone because I had to wait until it focuses to read and it strains my eyes. The text inside the phone could be bigger. 

The area could use some clutter to spruce things up like more posters on the ground, wild fauna or trash. Something that screams people have been in here before.

Overall, decent concept but too short to really feel anything other than being tense. I think it needs more sprucing up but the cliffhanger was nice and a twist!
