On the web version: introduction adverts load perfectly fine.
Game doesn't. (Just a black screen)
Delving further into finding some error log on the browser, I see that you've set the iframe to src="https://files.crazygames.com/sandtrix/8/index.html", so as to allow clipboard read and write. Why is this? The iframe also requests microphone as well.
Because I have default denied access to these things over practical security concerns, does this mean the game cannot run?
