More like meta info like "this looks like hidey hole, better keep close to it in case something comes falling down", you know, a bit like "this is a huge stash of ammo and medkits, I bet there is a boss fight around this corner", but I think you might be able to still narrowly make it with just lightning reflexes once the rocks do start falling down, and keeping track of potential debris shelters while trying to escape collapsing ruins is not exactly derpy vidyagame logic.There were a few things during ruins escape that verged on meta but they were still avoidable without no prior information.
Yes, I think in ruins escape there was a falling rock that, quite counterintuitively, can only be avoided by flying up to the cave ceiling and hiding in a hole. That obviously required some meta info (getting smashed by the rock a few times) in order to realize. It didn't feel that bad, maybe because the level itself wasn't as hard as the rest
There was also one charming object permanence/brick joke one that could be decried as bullshit by sufficiently... "modern" player - with rock popping up like a champagne cork, then crashing back down soon afterwards (seemingly out of nowhere to a sufficiently derpy individual).
