The screen shows "content://media/external/file/1571.."I did do that forgot to mention it
I just tested the Brave browser and if I put the files in
Android/data/com.brave.browser/files/Download/sluted
and paste
file:///sdcard/Android/data/com.brave.browser/files/Download/sluted/index.html
into the address bar, the game starts without issue - at least on a Android 10 device. It might be something changed for new versions (11, 12, 13?) but I don't have anything running that.Some people say that they can't access Amdroid/data/... at all, if you got a system like that - try the other method mentioned there - run it via File Manager + (should be a free download on the Play store). If all else fails - there's the online version.
