Weirdly I am unable to right-click to lower blocks no matter what I toggle on my touchpad settings. I haven't been able to figure out why either so I didn't go too far (Up to the spot you get the lotus to illuminate the place briefly).
Yeah I did. I can raise any block as much as I want except the one being stood on like you said, but lowering them is a no-go for some reason like right-clicking isn't registering.
