I remember playing Lode Runner The Legend Returns as a kid. My parents had a Mac Performa 6200 sitting around gathering dust, so I would mess around with it when I wasn't playing NES. The thing is still sitting around, but doesn't boot. Even took the time to replace the PRAM battery with the custom part that takes AAA batteries :(
I figured everybody had internal monologue. Sometimes when I'm at work and in the zone, in the moment I realize I'm not sure if my voice was in my head or if I said it out loud on accident.
I was thinking the same about that and when the navigation goes over the video. I feel like making the z-index of the video player higher would've been fine, at least the navigation wouldn't be hovering over it.
