I wallked the entire map, There are a lot of soft lock states where the ghost will not change its position and you can't leave the salt circle anymore. If you know the route to evade him it always works.
The ghost gets stuck on the bottom right salt circle,
the player gets stuck if you walk into the top left corner of the top left house,
The keys stay picked up if you die so you can get them, die, restart and instantly drive away.
There should also be some kind of indicator that you have to press g in front of the door or that you can just walk through the door.
