Thank you for playing!
Whenever you run out of moves you can go to camp and then rest at the campfire! You can then continue your expedition on the next "day" where you get another 3 moves. If you go back to town (shop) the expedition completely resets!
Digging is all about pushing your own luck, the longer you keep digging the more likely you are to find the most valuable treasures. But the chance of digging up cursed items (which drain your stats, can lead to game over if any of them reaches 0) increases as well!
