It didn't work very well anyways. You had to severely limit the C# features you used in order to target Flash. The majority of plugins didn't work, etc.<p>With their recent announcement with Facebook to make the Unity web player plugin experience more pleasant, this is much less bad news.<p>And hopefully they're working on an HTML5 target as well.<p>So, just another nail in the coffin for Flash at this point.
Brendan Eich played an unreleased Unreal Engine 4 (not 3) game from Epic using WebGl and ASM.js at JQuery UK last Friday.<p>I know Tojiro has already had Unity working unofficially on WebGL for a couple of years.<p>So I have a pretty good estimation of what's coming...
I didn't understand why Unity bothered trying this in the first place, so it's not surprising they gave up. The obvious places for Unity to go would be WebGL/ASM.js and NaCl (which I assume would be borderline trivial for them to support). It would be awesome if they revisited their "JavaScript" implementation and made it a bit less unpleasant to work with while they're at it.
