If I try to start the game in browser, I get this message:

[Error] call_indirect to a null table entry (evaluating 'Module["asm"]["Gi"].apply(null,arguments)')
	displayFailureNotice (index.html:248)
	promiseReactionJob

I dont know if its supposed to work in the browser environment. Im using Safari Version 13.1.2 (15609.3.5.1.3) on macOS Catalina 10.15.6.
