I'm working with the OP on the game. I took a screenshot of some of the warnings that we receive while trying to unzip and here are the ones that we encounter (not too sure if it make diagnosing the issue any easier):
Not implemented canvas addEventListener:
webglocontextrestored
Not implemented canvas addEventListener:
webglcontextlost
Not found getElementByld: c2canvasdiv
The game doesn't even make it to the loading screen. We did insert a custom load screen logo (but I don't think that is our issue....)
I believe our file is something close to 20MB
