In 'Chronochum: Whose Hello is it Anyway?', you play as a time-displaced linguist named Lexi Lingo, who gets pulled into a series of absurd time-travel mishaps after a rogue AI mistakenly confuses greetings from different eras. Each time period Lexi visits is a chaotic blend of hilarious misunderstandings and linguistic puzzles, requiring her to navigate historical contexts while dealing with wacky characters who take her attempts at communication far too seriously. Lexi must collect lost phrases across various epochs, from Shakespearean England to the distant future, to get back home while keeping time from unraveling and her sanity intact. The comedy escalates as mishaps lead to some unexpected team-ups, and Lexi learns that saying 'hello' may be the most complicated phrase in history.
