I am very sorry for the lack of a web build, but unity isn't having it lately, so a downloadable version will have to do for now.
Edit: I can't get any sort of web version working, I'm very sorry!
I had a similar problem. It helped to change the compression format (under publishing settings in the player settings) to Gzip
Sad to announce that any compression format failed to load in the game correctly, but this is a game jam game so I'm not making my hands dirty if there's no real need for it.
