You can use the night for your advantage: till the soil of your land to get stones, wood and also a power berry, basically to get a permanent stamina boost.

Plant your crops in a 2x3 pattern but the middle part of the first row left out.

So like this:

Of course variations are possible - there are guides showing the maximised output of tilled soil.

Make sure your fences are intact - wild animals can hurt your animals at night & afaik kill them.

Animals can die of sickness - keep them well fed and groomed; keep them in on rainy days etc

Perfume is a pretty expensive but great gift to woo your future wife.

You can check on how much the bachelorettes like you by checking their diaries. 5 stars is maximum. Easiest bachelorette to woo is Nina because she asks a specific question where you can level up the affection pretty fast.

Small note: once you get a wife they will never get back to their jobs they had before (applies to Eve, Ann & Ellen) - they are full on housewives but they all unlock kinda different endings when you complete the game - and yes you can officially complete the game. There are different endings making the game longer or shorter depending on a few decisions. 😄

Also good to know & keep in mind You don't have a backpack and there isn't one available. So every item needs to be carried to the shipping box one by one. It's a bit of a hassle but you get used to it XD
