Arranger is a puzzle game about moving, in both metaphorical and literal senses. Movement is the entire basis for the puzzles in Arranger, and is hard to explain without showing you (if you're able to watch the trailer that will be helpful). The world of Arranger is divided into a grid, and you don't move the main character, feisty misfit kid Jemma, across the squares. Rather, imagine that the row or column Jemma is on becomes a travelator, and you control the direction and speed of it. Jemma stands still and you move the ground, and anything on it left, right, up or down - like How To Say Goodbye but with more squares. It's one of those things that makes sense when you're doing it, trust me.
