This is such an interesting concept, I'm just hoping you can improve it. At Max World height where you have it now, the level is unplayable in landscape orientation. It also creates a curious and ultimately needlessly frustrating movement lag in trying to bring the center platform down, even when played in portrait. I get that you're trying to make it possible for the player to counteract the default slider behavior. I just hope you can uncover a more stable, less buggy way to implement it.
Everything all lined up and ready to go but then I realize it is the other right hand turn and have to send R back to where he started. As @Don G Rowe said, moving that platform was an effort but I was able to play in both portrait and landscape on my phone and tablet.
