Overall fun game. I do have some nitpicks, but they are minor (No pun intended)
1. The focus minigame I can put in a direction before it blanks out, so I can just quickly put the directions in once I have seen them.
2. I wish the shop had more upgrades since you can pretty quickly get a ton of money especially with rich veins.
While I do like the rich veins because they add an element of strategy it makes the game feel a little easy.
Good job for a Game Jam Game though it has a decent GB feel with the color palette and pixel art and has a good interpretation of "Old Gold"
