Presumably there was a technical problem now fixed. The Hint spoiler has disappeared but there is no rush if R is allowed to reach the winblock.
Having taken far too long to figure out how to reach the win, I did what I thought necessary, then waited and waited, but nothing happened. Happily, it was a glitch, because my next try was successful. I'll still give five stars because of the mechanisms in general, the novelty (to me) of the sliding puzzle and your overall imagination.
Super level! I really like the gameplay. But (in my opinion) there is one drawback - "the secret of the mechanism can be found out only at the very end !! then when I have already gone all the long way of puzzles correctly". It is impossible to predict how the mechanism works. This can only be verified. And then you can figure out how to finish the level correctly. But for this you need to go all your long way from the very beginning. In general, this level can only be passed the second time, if everything is done correctly. I really like the idea of the level. I love the classic geometric water puzzle! I really love this mekorama! This is my favorite. Interesting idea with three balls - I liked it. Liked the moving stairs for R! And of course the interesting work of the mechanism. Thanks for the great level! Of course 5 from me!
@Pratik Bhalerao you can try to put r instead..or get b to approach a different angle to the slider if you have time before it lifts..
Is autopilot required? I don't know how else to get to the stair in the corner. Because of that metal half pillar on one of the sliding walls in the water, I can only move the other sliding wall halfway over. Was this intended? Spoiler
@Buurmas No autopilot needed there. The half pillar doesn't block that other piece in every position. Keep trying, you'll get it.
I can win with B but not R. Spoiler: Winning With B I have B trigger the mechanism and race over to the slider hole and fall in. When the rod comes up, B stays on pretty well for me, and can easily walk to the win. Spoiler: (Not) Winning with R B herds R to the slider hole and R falls in. Then B triggers the mechanism. When the rod starts to rise, R just walks away. I've tried herding R into the hole from the two different directions, and I've tried having B stand next to R as the rod comes up. Either way, R just walks away every time.
Perhaps like @Neophyte, I'm tempted to go with 4 stars due to instabilities but have to go with 5 due to ingenuity. I gave up on trying to win with R, but thankfully winning with B is pretty stable for me. My video does show how you can win without the "ball on rail on stair" in the back, plus some outtakes. Spoiler: Video Solution
Such a fun level and B totally enjoyed visiting the farm! Had to go back and do it again with no tricks. Excellent and open map
