Trying out Sokoban-like game Cu-On-Pa (lit. "Cube on Panel") and what's really getting my attention (apart from the obvious English Country Tune similarities) is how much the devs seem to like kinetic typography.
This game's tutorial is very good at teaching the basic Rubik's cube-like maneuvers you need to even begin doing anything in the game – little tricks like "Moving in a コ shape preserves your colour horizontally" and "Applying the コ rule twice preserves your colour diagonally".
