Day 5 - good progress. Won't share any screenshots, because the game looks more-or-less the same, but the gameplay has started to fill out, and I play tested it on a friend.
Added many different creatures, spawn tables for different regions, rudimentary inventory, status, quest, and shop systems - and an ending, if you get to the other side of the map, hunt a moose, and bring it back to town.
Next up, I think, is exploration, to build up a sense of immersion - add basic fog-of-war to the world map, and add a Scout command that can reveal more of the map, tell you what animals spawn in a region, and give vague directions toward your current quest target. Once I have that, adding food consumption to limit progress, and a new quest chain to create waypoints/hunting camps, probably fills out a lot of detail in the world.
There's a pretty good chance I can get the above done today? If so, the plan for tomorrow would be to add ranged combat, and some actual enemies - bears, wolves, antagonistic humans, etc.
