xc.js has few ready-made classes; although it looks like you can do quite a lot of them.
With xc.js you make games that happen in “scenes”, not unlike Flash games.
The usage of HTML5 canvas is the biggest limit to the framework, as the games won’t work on older browsers.
However, xc.js does well to show you the potential that HTML5 has, and the games are suitable for many platforms (including iOS).
