It took a few tries, but I made it to five successful expeditions!
I can't tell if it's buggy or if the game really doesn't have any audio.
Also, I'm not sure how the pickaxe item is useful. I used it to remove a mountain (which would be worth +10 if submitted), to gain +5 but the /16 limit still kept the +10 of the mountain in memory, causing me to bust on my next draw of a +8 card.
