Cute art and I like the concept! All of the upgrades were useful and it was interesting to think about which would be worth getting vs just trying to go for the 1k gold. I think the biggest point of friction for me was getting back up to the top to drop off money. After a few day cycles, backtracking got a bit cumbersome. Maybe a one-time warp back to the top could be added as a possible item purchase? Had a lot of fun!
