Dear Hatsune Miku fans,
We want to thank everyone who took the time to make suggestions and report bugs. We understand the frustration with the lack of mouse controls and inability to see certain Chinese characters. We will be looking into these issues and will try to solve them as soon as possible.
In the meantime, if you find any other unreported bugs, please let us know in the following thread.
