Judging by the other comments here, I think I'm way behind. I've systematically EXAMINEd and SEARCHed every noun in the game, but I'm stuck. I have the bucket, crucifix and cloth. I feel like I need a rope or something to lower the bucket into the well, though I don't know why. I haven't found any bottle.
The biggest problem is how to get into the church, assuming you can. The door is locked from the inside, so I'm guessing it's not keys you need to get in. I've only discovered 7 rooms. Apart from the church, there's nowhere else to go. Or is there?
