Hi There,
Thanks for sharing your task 
After taking a look and trying to export to HTML I received the following error messange in the stdout window:
NotImplementedError: ‘cross’ shape is in development. Not currently supported in PsychoJS.
Removing the cross stimulus allowed the .js file to compile.
That said, I see you are also using a fair few noise stimuli in your experiment. I am not sure that noise stim is yet implemented in psychoJS https://github.com/psychopy/psychojs (calling @thomas_pronk and @sotiri to check) . If this is the case, then you might want to consider using image stimuli instead (so long as the noise is static).

PS. if you do end up creating images - you can do that very quickly using code - here is a demo showing how to do that for gratings PsychoJS is not creating my Gratings
