Mobile Sudoku

Hi,

Thank you for the plugin. It is really good, though there seems to be a bug. I have implemented the plugin on my WordPress site and it works perfectly fine on the desktop version. On mobile I cannot click on the Sudoku field and cannot fill it out. I have read that in HTML5 Touch has to be defined specifically, otherwise it is not working. And it should be defined for Android and also iOS.

Thanks a lot in advance for your help!
