Love the dwarf theme in this! The auctioning itself feels like it could be interesting, but not having any real recourse other than guessing to figure out when to buy hampers it a bit, I think.
I also would have liked to have seen prices change in the market over time, so you're always needing to check to see how things are looking. It feels like this gameplay could pair well with some kind of trading metagame, where you sell your goods to market. I.e. you buy out the stuff at auction when the prices are low, and then manage storage space to sell things when prices are high, etc.
Also, sad that the profit got broken with that bug. I also seemingly randomly lost at some point, but I'm not sure why. Perhaps also related to the bug?
