I'm usually not into horror games, but I enjoyed this one a lot! The atmosphere was great, the backgrounds and how you could explore the surroundings were immersive and the soundscape was creepy. Gameplay was really good!
A few thinks that could maybe be improved:
The exits were sometimes not clear. Not only were they on strange locations sometimes (in front of the petrol station, behind the station when entering the woods), but sometimes I didn't even realize that there were several different exits, especially when in the front of the screen.
I only figured out there was a body in the toilet because of the walkthrough. I didn't know that the exit lead the another room.
It was good to be able to skip walking, but right click felt a bit weird. Usually this is done with double click.
The time of day sometimes seemed to change from one screen to another, especially at the farm and tower.
Instead of warning the player to save before the shooting sequence you could have just implemented an autosave feature and showed the messaged "Autosaved". This is easy to do with AGS.
Having to a loong puzzle chain just to get a jar when there were so many containers lying around everywhere felt weird.
