Sorry, I should have done that to begin with.
Here's the console errors I get. Hope that helps.
Yep, as soon as I sent that, it dawned on me the browser on my shared computer must be set to block all localStorage, probably causing the non-loading problems I had with my own game (I wasn’t storing anything, but I guess Unity wants to anyway).
Sorry you had to remove that feature, but hopefully it works better for everyone now!
