As Matt said above - the astronomically low probability of "winning" is a feature of The Wretched, because the game isn't designed for you to "win". It's about telling a story of perseverance in the face of certain death, and clinging on to false hope. That's why I spelled out in the Debrief section that the rules of The Wretched lied to you - even though the game promises an escape with the Ace of Hearts, it was never actually going to happen.
Obviously this doesn't work for everybody, and some games in the jam are designed for you to be able to win them. That's great, and I'm really happy to see people playing with the system and changing it to do what they want it to do. We're also doing some work on the SRD to deal with the issue of the rules as an unreliable narrator, because this is problematic for people with specific kinds of trauma that I didn't consider when writing the original game. As soon as that work is done we'll be updating the SRD and I'll be updating The Wretched as well.
