Karst Cave

The route of this level is a bit hard to guess. Don't worry about the stars, if the route is correct, most of them will be taken along the way.
Low Ceiling & stop B is needed.

Spoiler: Hints

1、Red bricks are always a key reminder.
2、The internal communication of the cave is very logical.
3、A seriously misleading path is set up, and some balls do not need to be pushed.

Don't tell me to use the mekostudio customizer, it shifts the rightmost row of the level to the leftmost...

No 5* because i dislike one of the moves although the first time it was used it was well signposted as somewhere to go. I had a lot of random tapping in this level when i was exploring paths and trying to free pillarbot but at least that triggered one helpful move. Unfortunately the ball to free to free pillarbot didn’t work first attempt. This made me think i had incorrect gameplay for a while until i tried it again. I did like the red herrings.

Spoiler: Disliked move

the move when B is able to step up to a block that is higher

I like some of the gameplay but I dislike the same move as @ridgerunner. One can't realise that B is able to do so until one randomly tap on it. Thanks for sharing @935

Fun exploration level and you are right I never would have guessed that initial path from one cave to the other!
The mechanisms worked well and I was sure B was going to fall off of little righty but no issues at all
