I'm stuck in the room with the tower in the middle, you know the one with 8 sets of stairs and the cubes falling like a lava lamp? yeah, i don't know what I'm supposed to do next, I tried jumping between the platforms at the end of the room but i keep falling down

I've noticed that on the lava lamp thing, theres some sort of sound, it's kinda odd.

I´m stuck here too. Does someone know what to do next? I noticed there is a pink square with the help request in the front side of the weird lava lamp thing. But i can´t see if there´s something else to do. Also i can´t jump on the other side of the romm. Why?
