I got The Wretched and The Last Librarian in the Equality Bundle, and while I didn't have time to properly play through the games, they still deeply interested me; this included the mechanics of the jenga set and cards, because I am an incredibly odd person. I wrote a quick Java program to check the actual odds of victory. I figure this information might be interesting to anyone who already played a Wretched and Alone game, and especially to the creators, but will probably make the experience worse for those who have not played, so I'm hiding it behind this link. Again, please don't read through this if you haven't experienced a W&A game. This paste was written based off of The Wretched specifically, but almost all of the W&A games are identical as far as I can tell (mechanically, that is - you're really paying for the rest of the experience anyway).
If Chris or another creator doesn't want this information out there, I'll delete it.
e: It seems Balou85 made a similar (probably better) program, but I'm leaving this up because it's a top-level post and his is hidden in a comment.
