I think the game is really neat but I couldn't for the life of me figure out how to get a profit while digging. Still it plays well and is overall good for a solo effort!
EDIT: Also I'm a doofus that softlocked myself my first run by buying too much so I couldn't even afford a permit lol. That's totally on me, but it'd be cool to like, introduce the shop after the first run so the player knows the runs cost gold.
