when I use safe, it wont let me go further? Ok
I believe it is ok if you turn on autosave, but not when you save manually, because it is cheatable by loading the game again to one's own favour.
Just give me your password, and email in a WL mail, and I will unlock it :)
It is not safe to send plain-text email. A hacker can intercept and get the content. And it is generally advised not to give password to anyone (not even site admin).
I don't think it is a good idea anyway. What is the fun to let someone to beat it for you? You should play and beat the game yourself. You can't finish insane if you can't beat crazy.
