I'm really sorry!
As the first time to release the game, I didn't realize that there was this problem, and I'm really sorry for the trouble caused to you (ㄒoㄒ)
Thank you for telling me about this issue，I fixed it! b(￣▽￣)d
I've added a prompt to select the language on the download page for the time being.
Hope that helps. (； ′⌒`)
(Although due to code reasons (mainly my lack of ability) I can't do a full bilingual version for the time being)
