I found a new glitch that can possibly be applied to several areas in the game and save massive amounts of time. if this is already known, please let me know

Hello, me and AstralSpiff have been testing out an idea I had for the one puzzle where the cubes you insert are in random spots (puzzle to unlock red hand) and finally AstralSpiff discovered that it is possible to get perfect RNG to be able to reach all of the cubes from the top, not requiring you to drop down at all, saving a good amount of time. I am very sorry.
