One hint of an uncommon (and therefore not so intuitive) trick.

Spoiler

At one point you need to activate claustrophobia with R on B, just as R steps away from B. So R should not stay on B or fall.

I've seen this in a quite recent level, but can't remember which or by who.

I gave it a go but after too many restarts, no path was obvious as the rails darken the route too much. Basically, I was walking around blind.

Bufff, perhaps I have been overthinking but I found it really complex and obscure. And some times unstable. But after many retries I succeed.
I have to recognize it has many clever steps... Thanks!

@gmacpro Increase your screen brightness

Indeed, the level is dark. It was either that, or continuous unrecoverable R instability (the rails keep R on the top level, or prevent shortcuts). So yes, this concept will never be a perfect level.

@chemi, @cpw thanks for playing and rating.

| I give up as my R always fall out of place. I can't unravel the proper logic so it has to be so good and unreadable for me.

That would be from gmac's Be Strong, I guess.

@Block builder, perhaps it was Treatmnt Plant by @Darren Schrag?

@laurence.gr Yes that one, thanks!

I bailed out of this very quickly. In the first minute of seeing what moves what, the eye with its attachment got squeezed out of the level. I could see the rough gameplay which looked complex and always have trouble with an eye influencing moves anyway so decided not to proceed.

@ridgerunner The eye is only there to get a +0.5 tile height. It doesn't function as a blocker.

Very fun tricky balls/maze!! Once you know that trick it's a clean logic path although I did it with one different step,I mean...

Near the win block,I only used the zappers head when you used B's head...nothing important

I like this dark design too...Thanks for sharing and great job @Block builder
