No, I didn't realize it can go sideways. I just pulled a box with it & it's great

It would be cool, though, if the chain wouldn't go up straightaway but perhaps wait (maybe even a small pix like the ones you use to demonstrate the use of switches) until player presses the arrow key & count that press as a direction for chain (not as an intention to step left/right). It's a bit uncomfortable to press enter & arrow key at the same time (especially if player is, let's say, on the edge of abyss & has to pull the entity from the other side of the abyss.

But other then that it's very cool
