I liked the level design here, pushing you into using walls and barriers to align the two parts. I stumbled into a strategy that worked quite well (though perhaps not intentionally): getting one to jump on top of the other.
I was a bit confused as to what I was supposed to be doing for a bit, but eventually just sort of stumbled into it. The talking being the same key as the jump feels clever, though it meant that I missed a couple of dialogue instances, when e.g. I jumped twice in quick succession or when one of them fell out of view of the camera while talking.
I got to the point where the level flips around, and then they seem to just fall infinitely? I assumed that was the end of the game?
Anyway, overall a nice little puzzler.
