I've made a simple demo with C2 and exported it with HTML5.
The demo worked fine with Chrome, FireFox, IE.
And when I tried to test it with a China browser named "360" the demo returned message that shows it does not support HTML5.
But when I tried the games from Arcade section in Scirra's website with 360 browser, the games work just fine.
So is there anything that I haven't done that cause this problem?
