Thank you for your feedback!
I do agree that the wording could be a bit clearer so we'll probably change "...failure threshold by 1." to "...setback threshold by 1."
"Do not gamble" is simply a joke meant to emphasize the nature of the skill. We'll see if we can make that clearer by changing the wording a bit.
The "All Skills" box should only contain skills you've unlocked thus far. Maybe "All Unlocked skills" would be clearer.
It's worth noting that these changes won't happen immidiately. We usually wait to accumilate a bunch of fixes and then make a big update that includes all of them.
Thanks for downloading our game!
