Coffee script first level bug?

Hey guys,

I am trying to get past this first level (coffee script) and I am following what its telling me to do but I am still getting syntax errors. Here is a screenshot. Is this a bug or am I doing something wrong here?

Coffeescript seems to be down at the moment:

I believe you should use either hero.moveRight() or @moveRight(). The @ is a shortcut for accessing methods on this, and this is the same as hero in the global scope.

But yes, I believe CoffeeScript is no longer being maintained currently.
