@Frenzies I'm not quite understanding you, but I'm sure my hints (posted at the same time as your question) will help.
@Frenzies I understand. Definitely challenging and hard to have fun with when you're just swiping the screen all over in vain hopes. I personally prefer if they are peaking out a bit like in the excellent level The Ruins (also by @meko ) or The Cliffs (by @Mark69 ).
This hint specifically for @Frenzies Spoiler: Hint #4 The hidden draggable is under the bridge. It's a free single-block draggable. I am personally not a fan of free draggables as they are hard to control. In this case this one stays on the ground well (i.e. it doesn't flip over as larger ones would).
Very ingenious solution. Spoiler: What a pity What a pity that the yellow robot does not have to do anything
