Spoiler: Hint

you have to "dismount" the puzzle play patio, moving the 4 sliding borders and then the 4 pieces, to expose the win spot hidden under the center (you will only see the red light).
Have a good throw of the ball to the center pit!

Spoiler: Alternative way out

if you ever fail throwing the ball here precisely, or if the ball go escape away, a doorway may (or not, there are conditions!) let you in under the patio, and, by special path and precise view angle, you could manage to reach the win spot anyway.

changes: many fine adjustments. Closed a bunch of shortcut solving ways (B or ball further pushing using catapult, or touching winning spot by catapult at special angle) by adding fences on the patio center, then re-enabled alternate solution by reopening a ****. Added another fry-R, used some column pieces on the floor to slightly modify R trails when deviated by other drag actions.

changes: minor correction, a unimportant block was unwillingly removed.

Looks like a lot of red herrings in this level...

Spoiler

I opened the mechanisms up and rotated the arm and the ball fell on the win??? I didn't use the ramp or B or the Zs!!

You mentioned something about an alternative way - well it's so dark in there, how can one navigate????

@gmacpro wow you've succeeded the throw way!

Thanks for the rating!

Yep, there could be some .

well, this is already possible.

Spoiler: more details

you should enter from the door on right side, say, looking from catapult side (you have to turn around all the way, avoiding zappers). Two steps.

• First: External draggables should be already moved outside all the way. You have a sight point from receiving tower side, looking parallel to door wall, to move B internally until about half wall length (few cells move).
• Second: then you move the other patio pieces (B stays untouched in that position), and you seek for a special diagonal view, with much zoom, so you could spot near the win and send there the Bot. There's a tiny passage for it .

Note: I've yet found two different corner views, to do this successfully. With reference from catapult side as S, they are, from NE (easiest for that path), or from SW (hope to be clear enough).

I changed my rating as I was able to navigate thru the dark area. I'm no fan of hidden and that was HIDDEN but it wasn't complex or I was lucky. I didn't use your info under 'More Details' other than where to enter.

@gmacpro About red herrings, you could try my Deadly prison (very thought, time required: high, patience required: high)

@gmacpro Well done!

I did it like @gmacpro ...and in another way too...using a trick...not like you...maybe a bit hidden your alternative way....I like the catapult...Thanks for sharing @Alberto
