Sorry to hear about this, but don't let it dishearten you from making games and open sourcing them.<p>Someone stealing your code doesn't take away from the fact that you accomplished your goal of making a complete game. And from what you just wrote - that was your intention.<p>Regarding your blog title, I'd add 'timing' as well as 'marketing'. Titles of both submissions were remarkably similar ("Flappy Bird in HTML5" vs "Flappy Birdy html5 clone created using the Phaser framework"). Maybe the timing of your submission was off.<p>Also you can now state that you're the original creator of all the HTML5 Flappy Bird clones that have been popping up recently.
Marketing is definitely important here (<a href="https://news.ycombinator.com/item?id=7023467" rel="nofollow">https://news.ycombinator.com/item?id=7023467</a> / <a href="https://news.ycombinator.com/item?id=7201353" rel="nofollow">https://news.ycombinator.com/item?id=7201353</a> good timing + HN-specific introduction on this one: 300+ upvotes, made #1). But I think there’s at least another factor here: his version is more fun, because it’s faster-paced and has better graphics (obviously). So I’d say it’s also about more <i>quality</i>. Being more fun is more important than not being a rip-off in relation to quality too.<p>I totally understand why you’re pissed off, but I recommend trying (it’s not always trivial) to see further than “it’s all marketing”. Most of the time there are other factors at play, and nothing but good things come when you get to know some of them.
I'm not sure this has much to do with either quality or marketing. It's about stealing credit and whims of the internet in making things popular.
