I was playing it and i went upstairs, and BAM it crashes no error message or anything. And ofcourse my save file is gone. I don't mind dying but losing to a crash is unfair and i spent like an hour (first character had loads of fun). The game also lacks steam overlay. Great game and all but please fix the annoying random crashes, and add steam overlay!
No, it was probably the stairs that did it. This game hates stairs, and I think I already warned you about stairs, bro.
They know there are crashes and problems, and they are working on fixes. Give it time. With the saves issue, haven't had the game long so I haven't experienced it, but do what Pow said and just backup until it is fully fixed. About the Steam overlay; they said that they will soon add it, just some issues due to the age of the software they used for the game. Like I said, give 'em time.
