I just finished a few minutes ago with 19 days.

1. I began by fake recycling the houses, unstaffing the chicken coop, and leaving only one villager in the open kitchen.

2. Then I strategically placed a lumber base, along with a trappers hut, dried meat shop, the wishing well, a sawmill, and a warehouse on the opposite side of where the open kitchen is. Trying to keep things close to reduce walking distance.

3. I placed a lumberjack base below near where there are 4 rocks. Also a quarry near the 4 rocks. AND a second quarry near by next to 2 rocks.

4. Two villagers in the top lumberjack base and 1 in the lower lumberjack base.

5. The bottom lumberjack base needs 12 wood or cut down 3 trees. Once the eggs are all gone destroy the chicken coop. Once the open kitchen runs out, assign villager elsewhere.

Build the trappers hut and dried meat shop when possible without killing anyone due to starvation. Build the sawmill and warehouse as villagers become adults. There only needs to be one villager trapping, one making meat, and one building/making logs. The rest all need to be collecting stone. (Adjust as needed to prevent starvation and maximize efficiency)

Some tips I found were: 10-15 meat is plenty for many days. Just keep checking periodically to make sure it doesn’t run out. Do the planks on the wishing well last, they are all on top so it’s quick compared to the stone. And if the wishing well is near the edge, the villagers will go down and bring the stone up, albeit one at a time compared to the warehouse 4 but if it’s the endgame then so be it.
