A Video Game Decoding Ancient Languages

This is the official trailer:

 

 This is a full game video (spoiler alert!).  The game is called "Chants of Sennaar", and you can play it on these platforms:  Nintendo Switch, PlayStation 4, Windows, Xbox One

Players explore a structure inspired by the Tower of Babel – which the titular Sennaar refers to – full of people who speak fictional languages, represented by logographic writing systems: Encountered languages must be translated using clues such as non-verbal communication used by other non-player characters, illustrated signs, or other contextual clues. The player is aided by a notebook that contains the list of graphemes the player has encountered up to that point, and they may type in a word they assume is the meaning for a grapheme, which is then displayed above that grapheme the next time they encounter it. Once the player encounters enough graphemes, the notebook offers tests to see if a player has correctly translated the graphemes by displaying drawings of nouns, verbs or adjectives which the player must match the correct grapheme to; if the player correctly matches all graphemes to meanings on the page, those graphemes will be considered solved, and their real English meaning will be displayed above them – if all graphemes from a sentence are solved, a full English translation is shown. As players progress higher through the tower, they encounter new languages that must be translated.

Different languages have different writing systems and different language characteristics: some languages signify plural as repeating the word (e.g. "doors" is written as "door door"), while others have a separate grapheme for marking the previous or next noun as plural (e.g. "[plural] door" or "door [plural]"). Different languages also can have differing syntax, putting the predicate and subject in different places of a sentence. The graphemes themselves may also provide hints towards the meaning, with languages having determinatives (e.g. verbs, or nouns that involve humans).
