55th

Push the first ball in the trench back using the underwater buried draggable. Feel free to watch the video at 0:52 for this move.

@ohmytian Your comment intrigues me. What do you mean? That even at a logical level, this movement is difficult to deduce or intuit? Or is it a new movement? As I always do, I'll first try to deduce it myself and only refer to the video if I'm stuck.

@delator77 More of a precautionary step I would say. Its purpose is to ensure one move in latter part of the level works perfectly. I'm not sure how different devices might react so this is the best possible way I could think of. Of course you can choose not to do it, let me know what's the outcome later.

First off, I didn't understand your important message and got me thinking I was doing it wrong but I mis-read it and also didn't follow it.

I won but not without issue. The ball you pushed at 2:18 missed the half pillar below twice (it hit the rail and when to the white). This may be because I pushed it and let it fall without holding it and for the most part, it always rolled forward in the right direction with out B being present below. I pushed the ball you pushed at 2:40 just after the one at 1:05. On the move at 3:10, it failed on my first attempt. The next time, I released B faster and B fell off of the ball, the next few times, the mechanism didn't move far enough but I had not moved the ball as per your hint as I didn't understand it. Long story short, I squeezed the draggable and was able to push both balls and the mech to get the right position.

Overall, a nice B Only level with some mis-direction but I didn't fall for it.

Great fun and although i felt i was on the right track to solving the level, i had not anticipated the tilt which suddenly made obvious how the last ball would work. Always like misdirection.

@Meko Guy Wow, I didn’t expect you to win so quickly — congrats on that! Maybe you’ve already gotten used to my style of levels.

About the 2:18 ball — my apologies. I tested it on both my Android phone and MEmu, and it worked fine on my end. The 'B underneath' is just there in case the ball rolled the wrong way.

As for your solution at 2:40 after the 1:05 ball — I honestly don’t see it, so I must have overlooked something simple.

And it looks like my hint didn’t help at all either. Thanks again for playing, as always!

@ridgerunner The mech play is meant to be that little twist to catch you off guard. Not sure if my hint helped you out but anyways, happy to hear you enjoyed the bit of misdirection! Thanks for playing!

@ohmytian..didn’t need the hint.

An excellent level of logic that had me thinking and stuck for a while until I realized I had to change my strategy if I wanted to complete it. I thought my solution was the intended one until I saw yours. I was shocked, thinking that maybe I had inadvertently used a tricky move, and I played again to check it out. And to my relief, I found that my small variation fit perfectly into the logical gameplay. It's not a huge difference, but I recorded it for you to watch. Here it is:

Thank you @ohmytian great job!

Excellent!

@delator77 I think you and @Meko Guy both found similar solution. Good variation right there but I would say it also comes with slight risk that ball didn't roll the right direction. I couldn't think of a quick way to prevent that so I'll leave the level as it is now. Thanks a lot for playing!

@FXCX Thanks!

Very cool professional and difficult level. Reminds me of the style of @P_simorf levels. I really liked the multi-phase use of a three-block free element!!! The logic is SUPER!!
But I also passed it as in the video @delator77. Although in my opinion this is not significant since it does not change the main logical!

And yet, as always, I will say my opinion about the trick. At 1:18 and 3:05 - this is a trick - slider freeze. And immediately before it, "squeezing" is used, this technique is also not used in classic mecorama.

Of course 5! Very cool level

@Denis Nazin I agree with you that it consists of a few non-classic mekorama movements, but you are still able to pass! Thanks a lot for playing!
