01 The Game
Your voice is the controller.
Bribe a bored guard to get out of a dungeon, flatter a ghost out of her treasure, or squeeze a code out of a professor before the bomb goes off. It's a lot more fun than rehearsing how to order off a menu, and every door stays shut until you make yourself understood.
▎ Why it beats practicing alone
🙈
Nobody is watching
Rehearse real conversations before you try them on real people. Get it wrong as many times as you need to.
🗣️
Language people actually use
Practice the slang, filler words, apologies and small talk that people really say, the parts most textbooks leave out.
🎮
It doesn't feel like homework
You're escaping a dungeon or racing a bomb timer instead of grinding flashcards. You keep talking because you want to know what happens next.
