I'm sorry, end of the road. ಠ_ಠ
You won't be able to play this with Internet Explorer
because it uses CSS 2D Transforms and Transitions*.
Please consider using other browsers that don't spend
the whole day eating glue and thinking of times past,
and actually support modern** standards (even if prefixed), like:
Firefox, Chrome, Opera, Safari, Firefox for Android,
Chrome for Android, Chrome for iOS, and probably many more...
* I am aware that IE10 might support them,
but I won't bother if it's not even out yet.
I've tested all the rest.
** From two or three years ago. We're not talking WebRTC here.
