I'm like 90% sure that there's a fan translation of CK in Spanish already (because someone sent in an error message where an image file reference had been translated from "morning" to "manana" :P ) but I couldn't tell you where to find it, sorry!
Hopefully the translator will post it on the Discord fan-translations channel!
UPDATE: KevKlour has just posted their Spanish translated version in the Discord fan-translations channel! :)
