I haven't worked with Unity, but doesn't it compile to web?

Unity WebGL export is a big rusty bucket. It works but it's a) incredibly heavy, and b) the abstraction leaks and is buggy.

Unity is a fine game engine but where flash had a handful of abstractions you needed to make games, unity has hundreds. It’s never going to reach the same audience (as in the non technical devs)
