I really loved the atmosphere! The scarecrow was a good scare, but like everything else, it got bit stale as I got sent to start multiple times. I think there should have been few more landmarks, and or some mechanic to help you see where you have already been (for example stones or chalk). At start I though the teleportation just happened randomly which made me lose motivation until I saw dev's walkthrough. Even then the teleportations to an earlier point made the game into Getting Over It walking simulator.
I do think this type of game can be very enjoyable, but there needs to be more feedback given to the player to show they are on the right track. That or make sure that the player can't make the same mistake thrice.
Whenever there was a scare, it did get me on the first times. The rain did make the atmosphere a lot more tense and that thing with walls was creepy.
