it is invisible

Thulecite walls are only good when you don't have to craft it and they are provided for like PVE type gamemodes

This is pretty helpful. I'll look into it when I have the time.

well, i jsut try it, im liking it :)
i wish i could configure it to drain your sanity faster, like -1 sanity per second (or -60/minute) so repairing this things is faster
about the artstyle... i dont know if this may help you but: in Don't starve Hamlet, theres walls that are not player craftable but are pretty (from the pig ruins), so why not use those wallsprites instead?, here in this mod you can see the walls im talking about, the blue & mud-colored ones:

more specifically this ones are what im talking about, the orange blue ones:

i hope im helpfull :-)

this..this si BRILLIANT, and i wish you can further develope this concept: self-repairing walls huh?
imma try it and tell u later how it went for me

I'm aware of a bug that allows dark walls to be researched like any other recipy instead of always requiring the pseudo-science machine. I'll probably fix it later, or add it as a config option.
