Jump Over a Bug

@Sunny Sunset at least nearly three months ago you learned on Retrograde's Monorail Escape 2 that B can climb onto a block that is moved to a spot tapped on before B reaches it. I would suggest not being so crass by awarding a 1-star and demanding deletion of a level that you can't solve. It is why we spent so much time deliberating what should deserve a 1-star in this forum. "I couldn't figure out how to solve it" was clearly not a popular option.

@Sunny Sunset:

To solve this puzzle: 1. tap the grass spot beside the draggable, 2. before B gets to this spot, slide the draggable over the tapped spot, 3. B will climb onto the draggable from where you can tap him to the win.

You rated Monorail Escape 2 on page 3 of the comments section on 6 June 2016 with five stars: link.

Just an FYI, @zolv also did up a proper forum post regarding his new found observation (here).

As a bit of a repetition, here is what is going on:

What Zolv found here is something many have already discovered, made levels about, and even made tutorials on (as Scare Crow mentioned above).

Essentially what is going on is that after a reachable spot by B is tapped, B will be assigned a path to get to that spot and will then endeavour to reach it despite if the path changes. You could say that B completes his path on autopilot. There are actually many variants of exploiting the path completion (autopilot) algorithm.

In this case a single-block-height draggable is inserted into B's path. If the draggable was free or otherwise unobstructed, B would attempt to push it out of the way. Since the draggable in this case is attached to a slider, B cannot push it and thus must climb it. If the spot tapped was further away, B would continue in the direction of the tapped spot in accordance with the path assigned to him (his autopilot route). In this particular case the spot tapped is directly beneath the draggable and thus B will stop atop it.

@Propesyonal In this level you don't need to hold onto the draggable after pulling it over as it is attached to a slider.
