Chants of Sennaar is a language puzzle game that will have you scratching your head yet unable to walk away. Based on the story of Babel, you talk with the various peoples clustered around the Tower while trying to decipher their differing languages using only context clues. Certain glyphs, like "Open," "Close," and "Hello," will be easy, but it will quickly become harder to untangle the glyphs (and how they translate to the other languages).
The art style of Chants of Sennaar is absolutely stunning, but the developers also beautifully manage the notes system for the various languages, letting you leave yourself notes and possible translations before solidifying certain glyphs' meanings. Though the demo was only supposed to be 45 minutes long, I sat with the game for an hour before forcing myself to walk away and experience the other titles at the festival.
