most every other puzzle if you found all the pieces you knew exactly what to do and its this final one and the echoes of the eye stuff where it really wasn’t obvious.
Honestly I'm not sure how they could give you any more hints about this puzzle without just locking you in a room with essentially a copy of this puzzle and no other way out. The problem is you need to be in a place, and the physics of the Twins prevents you from easily being in that place. So you've gotta just figure out that the trick is to get to that place at the right moment before the physics can move you away. It's a reasonable puzzle imo.
Echoes of the Eye is a really weird DLC that was grafted ungracefully into the game and I honestly wish it was completely separate. You're lucky you didn't stumble into it because I've seen a new player do that and it's so confusing when you don't realize that nothing there has anything to do with anything else in the universe.
