Bimoji Training isn’t a first person shooter, and Mario doesn’t have a damn thing to do with it. What it will do is teach you how to draw Japanese Calligraphy. It will teach you how to properly draw those neat Kanji and Kana characters. The included stylus even looks like a traditional Japanese lettering brush.
It has an emphasis on taking tests and getting feedback from your virtual teacher, so it might have an educational feel. Still, for anyone who has ever wanted to learn the art of Japanese Calligraphy, this will be right down their alley. You can get one for $39.
