It just blinks forever. Is it normal?

can u share the following details:
1) game engine name 
2) file size 
3) have you watched this video : 

Unity, 189mb and just changed the compression format. How long should it take?

Got this error

Changed the compression format, got a build as Webgl and compressed into a zip file but it doesn't allow me to upload but I was able to upload it to here.

May I still participate in the jam? If you can help me, I would like to upload it to Lync
