The death of Flash was definitely bitter sweet for me. Working at an agency that mostly made Flash games/experiences from 2004-2011, there were a few years there after the final nail was put in Flash's coffin where we had to completely reset our expectations of what was possible in web based games (that run on the majority of browsers/devices). In most cases it was more time consuming and costly to build lower quality stuff. Granted, mobile devices were never a target for Flash games, so the biggest problem was that all the sudden our clients needed content to run on a new lower power device in addition to desktop browsers. Previously our biggest problem was clients that needed things to run in old versions of IE (IE6 anyone?!). Our last couple of Flash games that we built 5+ years ago are still far more impressive (on desktops) than any HTML5 game we've since developed (and we've developed A LOT of them!). GPU access was made available for the Flash player shortly before it died. A lot can be done now with WebGL, but wide device/OS/browser support is still a problem. We've since branched a lot more into native app development where we can continue pushing the envelope visually. Our JS games continue to feel like they have handcuffs on them and still can't compete with Flash 5-7 years ago.
