Lex Arbor: Learning an alien language

You wake up in an unfamiliar room. A strange creature stands before you, "speaking" in a language you've never seen. It's a language unlike anything you've encountered: built from circular structures and diamond-shaped symbols. To escape the place that holds you, you have no choice but to feel, learn, and use their language... and eventually, communicate with them. In Lex Arbor, the language is the puzzle. Pick up words through context, figure out the grammar by observation, and use the sentence editor to construct what you want to say.
