Koe is a game that teaches you japanese while maintaining the aspects of games. There are several Japanese characters you can pick up by traveling through the world. Through the use of communicative learning, the player will be able to connect the Japanese characters to the meaning of the words in the game world.
Koe features a traditional turn-based battle system, where you are given Japanese words from various sources (NPCs, chests, monsters, shops etc) and you use these words as moves in battle, you can even combine them to make sentences for better moves! For example, you may get the Japanese word for sword (katana/かたな) as the item (right). You can then select this word in battle to vanquish enemies.
