the way

I'm glad I didn't read the comments first. It was satisfying to figure out the pattern on my own.

Spoiler: Hint

I was able to decipher the pattern by looking back through the exit door as to where the sliders had rested to create a path. I just checked and you can do the same at the entrance.

I appreciated the elegance of this level. A simple and obvious concept is presented to the player in an artistic and cute design. Thanks!

I have missed this one. Thanks to @chemi 's comment to pointed it out to me .
I just did it and that's fine. Confusing at the very first and finally challenging enough with a good design. Thanks.
@chemi Difficult to give you a tip without a hint... Rails are your friends. You can't watch inside the box but enough to find out... the way
