Thank you for the comment! It is quite a challenge but I'm glad you played it and had enjoyed yourself.
I can answer that one confusing aspect - when you begin playing your Little One always begins with 1 inspiration (because meeting you is a wonderful new thing!). If your Wanderer succeeds on ANY roll, even with a penalty, the Inspiration goes up.
So if a challenge has an inspiration requirement of 3 it works as any of other stat, but it's based off of your inspiration at the moment. So if it's always a 3 then only a 1 would keep you from overcoming whatever you're facing. If your inspiration is 2 at that moment you'd need a 6 to win the challenge. (If you play it without the modifiers on the rolls everything is a bit more straight forward. Where 1 is fail, 6 adds 1 to your roll, and the rest do nothing. That helps curb the challenge a bit!)
