Thanks for the quick response

Actually it's just letters, so even if kana has a standalone meaning it doesn't show meanings, only transliteration.

However the program source code is *almost* modular and can be easily adopted to new languages or learning situations.

I do plan to make a variant of this for learning Persian (native language) and Arabic letters. However it should be easy to make other languages as well. As you suggested it can be useful for remembering meanings too.

For the contest deadline, I had to forget about implementing some supplementary features.
This will be developed more in the future.
