Just to let you know, I loved the game. It was (is being) well done ;^)
I don't know if you are from Japan, but I recognize the school (and lots of the scenery) as Japan.. I lived there for more than 20 years and taught there for 16. (I miss it so much, and hopefully will go back someday soon.)
I am guessing that the available renders are from Japan? (Even Japanese kanji, hiragana, and katakana)
Anyway, thank you for the story so far, and keep it up :^)
