Do you remember what levels you were on where the rules felt inconsistent? My main attempt with this game was to try and teach you the rules through the levels rather than give a tutorial. But maybe a small tutorial in the beginning would be good.
When swapping, if you looked at the help guide, you’ll see it says that “polar opposites swap”. However, “swaps prefer the X axis”. So, if you make a square, it’ll swap on the X axis.
