The customized cursor works but it's not rendered as a retina image. It's rendered as a blurry, 100% bigger-sized image.
Is there any way to force it to display as a retina image? (I tried both Chrome and Safari)
Here is some CSS. I just converted your PNG to a SVG and resized it. Feel free to decode this and resize the SVG in the XML.
