I have an unfair advantage--my computer is slow. Rather than 1.5 hours, I took around 3 hours. The only time the simulation stopped was when I saved the game (and I sometimes went to pee then). "Remove Structures" was only used twice, to remove the original cart and to vacate the boarding house (in year 4) so people would pair up.
I think I have everything: all required buildings, lots of food, 4.5 hearts, 5 stars, everyone housed (in a boarding house and 2 wooden houses), all warm houses, everyone tooled, and a squash harvest in year 9. In addition, everyone was educated--with 8 starting kids that was a surprise. (I meant for the tavern to make ale in year 9, but I forgot.)
In early summer 3 I noticed that someone was without a tool. I forgot to build a blacksmith! Eventually, over half of the adults were toolless, including the blacksmith. But when he finally delivered 6 tools to the storage barn in early spring 4, most adults got tools, including the blacksmith.
The hunting lodge in the forest wasn't catching many deer, and I was worried about keeping people clothed, so I built a second hunting lodge in year 5. In year 6 the new hunting lodge (with 1 hunter) caught 3 deer, but the old hunting lodge (with 1 hunter) caught 5!
I enjoyed this challenge a lot.
Hmm ... I get an Internal Server Error when I try to preview or post with screenshots. It's getting late--I'll try to post the screenshots tomorrow.
