Game fails to load. I hit F12 to get the browser developer console, and found this error:
"Uncaught ReferenceError: unityFramework is not defined at HTMLScriptElement.r.onload (Nursing Homes Suck.loader.js:1)"
I had this error too :] Here is how I fixed it:
Go to Edit -> Project Settings
Find Player -> Publishing Settings -> Compression Format
Set it to "Disabled".
This will make your submission larger, but unless it is a HUMONGOUS game, it shouldn't matter.
