@Lang Tao Jin Don't be in a hurry, just stop for a moment. Win block is very tempting, like the sound of sirens in the ocean.
Very interesting trick level. A very cool idea of how to unlock the victory block. BUT! There is great instability. If B takes a star and leaves right away, nothing works! It is imperative that B stand in the place of the star for a few seconds! Since your mechanism is hidden, the players do not understand this. To make B stand still, I would do like this: Spoiler: For B to stand for a while
@Denis Nazin Thank you for playing. But it's not instability, it's part of the game. I've put a red brick, that's enough for hint (probably because there is water so it is less visible).
