LangLingo and the review

LangLingo has no word lists to memorize: it brings back the scenes you lived in town.

Someone says a line you've already heard in a mission, and you answer. Each line comes back on the right day: tomorrow, then in a few days, then in a week. Got it wrong? It comes back sooner, until it sticks. Practice every day and you build a streak.

The goal isn't knowing rules. It's that, when the real situation comes, the answer comes out on its own.
