Opening C2 games without Node-webkit?

It's possible to export to HTML5 and play it online. If I wanted to play it offline,I need to download some offline server or something like xampp.

Why can't I just open the game, c2 says browsers usually block certain features when the game is played offline.

Is there any way to do something with node-webkit and play it in the normal chrome browser?

Anyone?

Construct 2 games already work offline in web browsers, but only when hosted on a real website (you cannot run games from disk unless you use the node-webkit export).
