Hi Guys!
BitBalloon founder here - noticed some traffic coming from scirra.com and found this post.
Thanks so much for the support 
pedropss, as a small startup this really means a lot to us!
One thing that makes BitBalloon a great place to host HTML5 games, is the way we automatically package up your assets when you deploy, so you end up with a minified bundle hosted on a CDN with far future caching headers set.
This means that when people access your game they typically only need to download all the javascript and images the first time, and then when they come back to play more it's all been cached on their device.
Really excited to see people host their Construct2 projects with BitBalloon.
Let me know if you got any questions or suggestions
