Learn hiragana (minigame?) for renpy (Patreon)

A while back, I've written a little script to aid me with learning hiragana, and maybe katakana later on. It was sitting on my hard drive collecting dust. This weekend I've deiced to update it, improve it and upload it for you to use.
It can be utilized as a minigame or puzzle maybe, and you can modify it for any other similar use as well.

Doing this gave me the idea to make a similar system for words and phrases. After all, it would be the logical next step after the alphabet. But I will need sounds and images for each word, and that requires more than just the programmer. I will try to reach out to voice actors at some point. But until that, we will be back to our regular minigames.
