The site has some issues on tablets, simply as the scroll event doesn’t fire until you stop scrolling, and so the animations don’t trigger continuously like they do on desktop browsers, only when you stop scrolling. It didn’t crash when I tested it though.
Unfortunately, as it’s a side project, I didn’t have time to rectify this (using iScroll or something similar). Would like to find a solution though.
This could be something I look to include next year though if there’s interest in finding out about usage.
