Not sure if i have the designed win. My first two were not as they missed differing amounts of the level. An attempt at a third win was scuppered by a hidden zapper , but a similar gameplay led to my final win which used everything apart from one draggable perhaps so may be the designed way.
Too bad the mechanism wasn't smoother - I've won three different ways with auto pilot (tap and move the slider).
Found a solution, but it required a trick, so I`m not sure if that was intended. Looks like the level has multiple open paths and a shortcut. I did not run afoul of the hidden zapper.
Good solution, but this level has a lot of shortcuts you don't intend, so you need to be careful and design to protect your level, avoiding players using the way you don't want. Thanks for sharing.
