I think the main problem is that right now, the micro:bit version has too little memory available to be much use (1v87 used to be better). I've filed a bug to try and fix it (you can follow it here) but I'm a bit busy right now.
In the mean time, anything you can do to get memory usage down is good - so if you just remove all the comments and stick everything on one line, that might make it work for you?
