I found all the items. So I hope I got the special ending :) (There was a heartbreaking beautiful scene)
There is no saves (I think it's not good, because you may need to play about couple of hours to find all items).
It was funny. Thank you!
P.s.
There was a quiet sheep sounds near the camp, So I tried to find anything near the camp but I couldn't. I don't know what it was :))
