Doesn't work for me. I will wait until you make it standalone.
The browser could not allocate enough memory for the WebGL content. If you are the developer of this content, try allocating less memory to your WebGL build in the WebGL player settings.
I saw this problem once on a computer with four gigabytes of RAM and Firefox. Before the app was running, too many tabs were open in the browser. Thus, after closing tabs, the application could start normally.
When compiling the applications, 256 MB is selected by default for it to work, I found that, although it is not enough to load ALL the pictures of ALL locations (which requires considerable time and patience :-), that will be enough for normal use. Hmm. I can not say anything definite yet, I need more information. Perhaps there is some way to control memory, I will try to examine this question.
