I bought this game last night, and I've played maybe an hour or so of it, getting the hang of it. I read up on the rules and I think I've gotten the hang of the Game of Similarity -- however, the selected cell (the one that is the "cursor" so to speak, the one that functions as an axis around which other cells rotate) doesn't let me move to the edge of the map! There's rows and rows of cells that I simply cannot access, and I can't seem to figure out why. I don't see any apparent boundary line anywhere in...
