Ruby Room

[A Player]

Sorry if this is the wrong forum to be sending this in. Currently, I am in Ruby Room and I have been struggling for a while on this area idk if i did something wrong or the answer is just simple asf and I'm dumb. I'm following a tutorial and there's meant to be rocks that lead down but they aren't here for me. Please if anyone knows how to fix this tell me.

My guess is there's a red crystal you have to activate somewhere (maybe to the southwest up that rock wall?) where you can still get back to where you are now. It's been a while since I did this puzzle tbh and I can't check my own save file right now, so I can't give you anything concrete.
