for me I have windows and it won't let me look up or down. I don't know if I'm missing something or not because I originally just wasn't on the right screen to move :/
I figured it out!! I dunno if it'll work for you guys, but on that screen when you first get to a floor, just look down, is the screen you look around in. when you look at the wall you wish to look at, then you press Z! I hope this fixes your guys' problem i'm just dumb lol
