Thanks you! I should have updated this a long time ago, glad to see it taken care of ❤️

* Remove some swearing from descriptions, it's a personal choice but it feels more "professional"

I must admit that I liked them occasionally, since it can convey that the project doesn't take itself too seriously. Because generally I don't believe a gaming project has to come across as strictly professional. But I can see why someone might not like this particular swear word.

Maybe we could have swapped it with something more mundane (darn, frick, ...) to still convey the joking atmosphere if you know what I mean. But quite honestly I don't have any strong opinion on this. If you think it is better without, then it's fine by me too. Definitely let me know your opinion is on this!

Yes, jokes are cool. But I think "fuck" is maybe a bit too strong.
