I am just giving a few rather than a full one but i might make a full one if i feel like it.
The 1. Thing i want in the world is to make the merm kingdom feel like a Merm kingdom.
There is just the king and merm guards, nothing else related. We need fishermerms, We need more Important Wurt Exclusive structures for her merm city, i will give a few ideas on this:
Declair-mermtion Station:
▪This is a structure that can be built, you make if anywhere, but you will probably want it near Merms. They can hold 3 Doctorines.
▪Wurt is able to declare and craft Doctrines. Each one has a unique cost, but each one always includes 3 Durians and 3 pig skin.
▪You may put a Doctrine in a Declair-mermtion station, and all Merm buildings, and the Merms that live those houses (They keep the buff even when far away from those houses) will gain those buffs. I am not sure if this should be global or work in a radius i am not sure what is better, you may suggest ideas or improvments.
▪Some Doctorines may give merm's a special ability, make them better at something or buff any new Wurt structures.
Also add fishermerms please.
Edit: I like the idea of Wurt somewhat being able to automate things in a don't starve balanced way, i made a few ideas below in the comments, and you could share some too.
