The first part took an hour, the other two took 43 and 39 respectively. That's with doing and buying everything I could. As far as a prestige goes, it could be sorta a closed loop like meteors and fog crashing down again when you click "NG+" but bringing a few animals with their torches. I suppose your pets or villagers could be immortalized in some menu for small permanent buffs fitting their themes, but also a currency that unlocks things in a post-game list. Called like embers or something. Just ideas, obvi. The game definitely accomplishes a lot, so it doesn't *need* more necessarily.
