Quick errata and precision, as I won’t be able to update the files before some days:

When discussing “better results”, it’s meant to say that A success with a difficulty is seen as a better result than a failure without difficulties

Concerning the deck, when it’s empty you simply have to reshuffle it and put it back in play.

I hope you have fun if you try the game and in any case, thanks for taking time to look it up!
