Not bad! Sounds like the tooling has improved since I last looked.

How about debugging? Is it possible to step through a mix of C and JS stack frames?

The Chrome devtools have added experimental DWARF debugging support, but for big projects that's still a bit of a hassle:

The embedded Javascript can be debugged as usual.

In my case I usually debug the platform-agnostic code compiled natively in IDEs like Visual Studio or Xcode, and for the HTML5 specific code (which is just a few hundred lines) traditional "printf-debugging".
