You can try OddSparks :) the main goal is also to harvest resources and make production lines but it has really cute visuals. I feel like the logit is a little different than satisfactory so it's fun to try to figure put different approaches.

Hmm didn't realise there could be reason to not use a second ship name. Is there a specific reason why you don't want to use jayvik? Feel free to DM, I am really curious

"Kráva" - means cow, most common feminine swear word, kinda like "bitch", use "krávo" if you are directly talking to the person you are cursing out
"Debil" or "Kretén" - means idiot, masculine, vocative form is "Debile" or "Kreténe"
"Jdi do prdele" - means go in the ass, used as "go fuck yourself"

Swear words:
"Do prdele" - common thing to exclaim in a negative situation when you would say "fuck", translated means "in the ass", way harsher version would be "do píče" = "in the cunt"
"Sakra" or "kruci"- again exclaimed in negative situations, closest in English is, I would say, "damn it"

Endearments:
(All are in a form when you talk to them - vocative)
"Lásko" - love, straight forward
"Miláčku" - darling, to me feels less sarcastic then "darling" tho
"Zlato" - means gold
"Brouku" - babe (might sound weird but literally translated means beatle :D), "broučku" is more endearing form
