The box moving games have been done since games started being a thing, but being able to move a box only once changes the mindset you have to have when confronting the puzzles. Blocks moving also in one direction are a nice adittion that gives diversity although the level designer should be careful because sometimes they give away the solution quickly.
Theme, only one movement per box, some boxes move only in one direction, fitting.
Originality, it doesnt stray much from the genre but the twist on the mechanics brings life to it and a breath of fresh air.
