What about just some partial censorship, like there would be a black bar on the majority of word, but the significant part (to recognize it) would be visible. Also, you could put some simillar-looking characters under the bar, not to be "fuck" but "luck" for example, and show only the lower part of the word. Also, "Euck", and show the upper part.

Or just invent some swears in "knytt language", which could simply replace it. As strong as they could be, and use them in common phrases with "fuck" to be clear what it is.

BANG, another tileset!
I'm also planning a nightmare version...

Again, for sample, check the first post.

As I've said, I've finished Pines tileset.
Here it is!

Used sample is at the first post's tileset's description.

Hello!
I just want to share these tilesets I've made, since some are not used in levels and I think I won't use them either, so it'd be bad to keep them for myself...
All of them are for public use of course ^^

This list would grow as I'd make new tilesets 

Oh...I'm a bit late...but...can I apply to this tileset remix action too?
I haven't done any tilesets lately, so I'd like to help out here

(I not intend to mess sergiocornaga's business though, so if you wanna only one contributor, go for him ^^)

Great!
Finally someone continues the wiki, the ultimate source of information ;D
Yay!

Hmm!
I'll try too...:

I live here for years! (moved there few months ago)
Everyone here is, like, my super friend! (they barely say hello)
That what you say was interesting as hell, even now I am soooo impressed! (barely know what are you talking about)
I can speak in every language you choose! (can only say "hello" in 3 of them)
My shop is soooo popular! I've already sold tons of things! (1 customer during her career)
Be my friend! I am the friendliest person around here! (persuades you to be her friend so hard)
I know EVERYBODY around Knyttworld! (doesn't know your name)
What am I doing here? I should be an actress somewhere in Hollywood! (can't even pretend the truth while lying)
My clothes are, like, SUPER AWESOME! (wears garbage-like something)
Check out my garden...There are lots of beautiful flowers there! (something dead/strange there)
Look at my house...it's SOOOO big! (but it's really small)
What do you think you're doing? You're LOST???!!! Let me see the map... Ah I know this place PERFECTLY, let's go! (gets lost herself)
How dare you talk to me like this? I am the wise here! I could even be your mother! (is almost the same age as you)

 
I am not sore/annoyed!
I really understand your thing, but I see that my next efforts would be useless.
So, my efforts lead in the dead-end, like those. 

But: much thanks for appreciation!
