Hooray! Good news: the game is functional. I just ran through a week and a half of gameplay with no major issues and not many minor ones.
At this point, it's time to double down on the RPG half of the game. To expedite things, I was playing without visiting dungeons, which gave me a surprisingly hard time of things. (All of the dungeon-exclusive ingredients are available in town one day a week with a 20% markup, which is the only reason this is even possible. I'm not sure you can win without at least shopping from the dungeon stores.)
I am pretty well satisfied with the first dungeon. The second dungeon is mostly done but needs to be populated a bit. The remaining dungeons are skeletons for now. Once I finish developing the dungeons, I'm going to add a few more events and sidequests, and then I can call this game done*.
*done enough for testing, that is
