hmm i don't know much about code (i could barely put together the ui) so i'm not really sure the root of the issue. are you able to play other games made with sugarcube? if so then it's definitely just a me thing, but unfortunately i don't know what it is
I don't know if you found a solution yet but I know one if not! Chrome isn't gonna let you play this game, you'll have to get another browser like Microsoft Bing or smth else. I have a samsung btw so this is what worked for me after chrome wasn't working.
