> PDF forms now support JavaScript embedded in PDF files. Some PDF forms use JavaScript for validation and other interactive features. As far as I can tell I still can't play breakout in a PDF in Firefox though (and I think that's for the better) [0] [LINK] [1] [VIDEO]

Support will vary by viewer, but Chrome's built-in PDF viewer supports a subset of Javascript. It's enough to play Breakout inside a PDF: [VIDEO]
