Good product but...
This is a good product that fulfills its functions of learning kana.
However it has some flaws that can sometimes make the game experience a little irritating: the stroke order is not always respected and it is impossible to finish the exercice in which you must write a complete sentence because the system does not recognize the final mark (I asked a Japanese friend to try ... nothing works).
But overall good game that will help you if you start learning the kana ...
