Yeah, I noticed that as well. I interpreted it that stoicism forces a certain way of thinking that can lead to very bad outcomes with certain way out. Effectively a one-way path with no exits and no way to reverse course.
The stoic becomes its own trap.
Stoicism: you can however lock yourself up, ending with no valid direction for next move. However, the game doesn't end, so you have to restart. There's probably a philosophical implication here, though I can't think of one.
