Black Screen HTML5 Deployment itch.io, Kongregate

[Nza3]

Having this problem, and hoping for some advice.

I've read some other threads on this problem. I've tried eliminating all of the .m4a audio files. I've tried setting resolution back to exactly 812 x 624. I've tried moving the project out of private mode. Any other suggestions are greatly appreciated.

Thanks a lot

Got my game to load, the issue ones the inner directories must not be zipped because only the main file you upload gets unzipped on their server! but now always getting: Type error cannot read property 'length' of undefined when I load my game on HTML.

Is there any reason it loads perfectly in playtest, but even when changing nothing, it does not load in HTML and gives the above error?
