Thanks for the feedback, inconsistency was something I was thinking about in my design, to another type of block that has not been implemented which is the gray block, this could not even be moved (more inconsistency).
But I don't consider it a bad thing, in this case, I think of the blocks as powerups. And I think that not limiting things would make the creation of level design more difficult (long term), with the player creating the same solutions for "everything"
