I can STRONGLY rec
Chants of Sennaar to anyone who enjoys deduction/puzzle games, and in particular the micro-genre of games that have translating a conlang (in this case, multiple conlangs) as their central mechanic.
Looks like
Sable, plays like a cross between
Return of the Obra Dinn and
Heaven's Vault.
(It makes the excellent choice which
Sable also made and which more indie games should go for, namely putting all your characters in face-hiding hoods or masks so you can completely avoid uncanny valley bad face animation and spend your resources on other things instead.)
Made my brain ache in a good way and made me feel clever. I did have to draw maps (my spatial orientaion is terrible, so others may not need to except for one specific maze-like area), and make assorted paper notes to solve various puzzles.
You have to not only successfully translate each language individually, but, later in the game, interpret conversations between pairs of languages. This requires knowing that the languages have different word order -- in a very simple way -- one language does object-first Yoda-speak, several languages vary in how they form plurals, etc., but you do have to be able to translate in a grammatically correct way, not just word by word.
And to get to the "true ending," the game requires you to go all out and "speak" the languages, by using a given language to correctly describe a picture you are given (with no text).
I admit I did get a tiny bit emotional when I made it to the end.
Has a subsidiary stealth mechanic, which I mostly enjoyed; near the very end of the game, it did briefly hit the point of requiring a somewhat quick response, but was still ultimately within the capacity of my abysmal reflexes. Nonetheless, it's not a zero-coordination-required game.
