You can change the language from “Options” on the title screen.
You can also adjust the key bindings there. If you're having trouble with controls, I recommend using the keyboard first to reach the key binding settings.
Thanks for the report.
I haven't received other reports of this issue, and it works correctly in my environment, so I’m currently unable to reproduce the problem.
Could you please provide some additional details?
Also, if you're using the web version, I recommend trying the downloadable version, as it may work properly there.
Thank you for your cooperation.
