Welcome to the forum and thanks for posting a level. The route was very straight forward but a nice starting level.
Welcome and good start, at least better than me however the level can be won by simply moving the top bot on the slider to the win point...
Hi and welcome to the forum. As others have noted, a direct win by moving the top R directly to the win is possible. I suspect you got fooled by your own optics and didn't see that those two floating platforms were on the same planes. Otherwise a nice basic path if you choose to use B.
