I'm still fixing the stability issues in the level I posted and deleted a few days ago. Instead, I decided to post a different level instead. Spoiler: One Trick To Be Used and Hints Only low ceiling/claustrophobia is required. Place B beside the "draggable at rest", "slow draggable" (or whatever you call it) to let it move. The motor somewhere in the tower is there for a purpose. The ball that will roll over the fence has to be placed in a good position. It might fall somewhere else unless you use "someone" as a "wall". The ball will "push" or "block" the "draggable at rest".
Yes, strange level... fun effect but hard to sense... eskerrikasko partekatzearren/thanks for sharing @P_simorf jauna/sir
Since this level was posted I've won but by throwing Robots. But somehow I don't feel happy. So I tried it again this time. I zoomed in to see what was under the slider. I know what I have to do And now I've completed the gameplay properly. Thanks for sharing, it's a really good level.
