I can't but apologize for the gameplay, and especially elevator section (aka the water level of this game.) It's very thrown-together and just not very intuitive.
The original plan was to have Mother narrate a bit more as you do things, and have something a bit more interesting than all those parts lifted by the elevator (e.g. one of them being a magnet that zaps the next part off a cliff or something.)
But that's what happens when you spend 10 days on the visuals instead. And that work at least seems to have paid off, which I'm glad to hear.
