Hey, found a glitch with the Sunken Temple where pulling the blue lever in the room with all the rocks says it's drained water, but it hasn't actually appeared to done so?
There's also a glitch where you can run through the hole to get to the next area before the trigger where the water send you back to land plays.
Due to this I was able to continue on, but found that one of the green levers, the top right one from where the save crystal is, doesn't have those little water jets on and the green lever can't be activated. It's blocked by a pile of bones which then temporarily turns into a barrel, when I interact with it, before switching back to the bone pile.
