The sleeping game is broken. Some text is not displaying, the text is missing both in Mandarin and in English translations. When you click on the sleep button, no text displays. There is no text displayed next to the tasks in the sleeping game (top, left). When you click on the action icons (orange circle) nothing is shown.
I think it is most likely an issue with fonts. Maybe you can test this on another persons computer?
Also, some parts display but do not have English translation.
