I am planning a game that should come out in 2013, but the program I'm using doesn't support SWF files and I heard that's the only way to get a game on the site. So my question is will there be HTML5 support or and other exporters in the future?
Dan has said himself that when HTML5 makes enough of an impact, and there are enough ways to secure intellectual property, that we'll investigate HTML 5. Until then, we are Flash-only.
