I know someone else has it too.
I don't know. I played with it for about half an hour, and it seems like I'm missing something. Every time I think I've got the hang of it, the game indicates I'm doing something wrong. I need to get a FAQ.
I can read hiragana and katakana (though I don't always understand what I read), and it isn't helping with this game.
Since that half hour, I've been playing Chou Sojuu Mecha MG and have gone back to Daigasso.
Honestly: get Chou Sojuu Mecha MG instead, unless you have your heart set on puzzly things.
