Surprisingly I got it as I'm not too good with invisible type levels. BTW, welcome to the forum and I look forward in seeing more levels maybe with more game play.
I finished it too, but I'd rather not give a rating. Although the title is fitting, the "invisibleness" turns this into a guessing game. One way to improve the level is to add a code or some hints into the decoration for the player to decipher. Another would be to put the sliders on rails so that they would move in more confined ranges. Sliders without rails have a tendency to crash through other blocks and make the level unstable. Otherwise a clever implementation of Mekorama. Welcome!
