[Feature request] "Undo move" for the move counter

[fabiorzfreitas]

Well, for starters, I've never noticed that in this game, there can be no more than 1 move in a direction (up, down, left and right).

As such, I often make simple mistakes when playing on the keyboard (as opposed to clicking on the tile I want to move). I find myself doing "right-left-intended-move", or "down-up-intended-move", simply undoing my last move because of something which may be considered a misclick (is there a proper word for keystrokes?).

It would be very nice if immediate opposite or back-and-forth moves could be deducted from the total move counter (or perhaps from a second move counter)!
