You lead the investigation by writing to the characters, and the game corrects what you write. You practice the language without leaving the mystery.

The game explains each correction simply.

Corrections off
Turn on corrections to choose your language and start a game.
Language to learn

With academic mode, your answers are corrected during the game.
No vocabulary lists, no fill-in-the-blank exercises. You lead the investigation, you question the suspects, and every sentence you write becomes a chance to improve: the language is learned in context, driven by the urge to solve the mystery. Academic mode corrects your answers as the game goes on and explains your mistakes, and because this learning is tied to the investigation, it stays in memory far better.
