I've got mostly the hang of everything but is there anything particular we can do in Good Princess Castle with little movements to clip through the floor/ceiling early, or is it down to luck?

Oh and can anyone explain in some better detail the rng manipulation in Lake? I must be losing a few seconds there.

I have a setup in the GG version of the game for GPC clip. its hard to make perfect but with practice its more consistent. I have a guide in the GG versions page.
