the way we render TTF fonts is rendering them to a texture, and do not just scale a low-resolution text up on high resolution devices but render it in retina mode so your fonts are crisp on all kind of devices.
For Http request, the XMLHttpRequest component will be your friend. 😉
Local building is currently supported for the desktop platforms Windows, Mac and Linux and for Symbian and MeeGo. For iOS & Android, our build server allows you to build games for iOS & Android within a minute and then just scaning a QR code to deploy the game to your devices. This gives you the option to test your games on multiple devices easily, and to develop and test for iOS devices from Windows without a Mac. We will add the option for local building in early 2014.
