HTML5 is platform agnostic, so not really a "PC" issue. If you mean exporting, there's a few options in C2, but out of the box, only HTML5, that work on browsers.
Any game you can do with CC you can do with C2. Basically, anything you feel like doing.
Of course, there's some easier to make than others. Just try it out and let C2 show you what can you do or just make a concept in it.
And reading the tutorials also helps.
