Hi Wardod10, thanks for comment. You may only switch black dot with one of neighbour ones. If you move too far and no switch is possible, the black dot returns to it's place.
The tutorial is super quick for how big the game is honestly. We don't want people to skip it and miss useful information. That and Mr. B needs to tell you your business! ;-)
It actually just a GIF. Nothing special honestly. I have no idea why more devs don't do it...? It's great to know that it caught your eye though, that was what we were trying to do! :-)
