Thats very vague. So you can get to day 19 but get a bad end everytime? The actual day is important because as in the title the VN needs you to find passwords in the text to avoid bad ends, and there's alot of passwords. So simply saying 'the whole route' is not easy for anyone to help you.
If you do literally mean 'i want everything spoon fed to me with every password', you aren't going to get an answer because that would spoil it for anyone else trying to do it themselfs and only wanting hints from the comments.
