At first I wasnt really expecting much from this app but after a few game plays it was very entertaining! A simple way to learn hiragana by using rhythm.
The only downside of this app is that it does not care much about penmanship when practicing stroke orders, or giving a few extra seconds to write it out since most people downloading this app are probably beginners in hiragana (like myself) ... So -1 star for that.
