Janeeja is an addictive game where you need to guess your word before your opponent guesses his/hers. The opponent will ask questions that can only be answered with yes, no or "i dont know". If you win a game you earn crystals with which you can unlock nifty bonusses.
Janeeja lives on the planet Kepler-22b. His solar system has a lot of crystals, but little variety in words and language. Therefore, Janeeja has asked the Earth to help his people communicate, by building a strong language. In exchange, he will deliver valuable crystals from the core of his planet.
