The first time on this puzzle I had no real idea what was going on. I was also a tad concerned that the flashing and strobing was going to bring on an epileptic fit

.
After some time and by pure chance I completed it, and carried on. Of course I forgot to save the game and got thoroughly killed a few minutes later.

It was five minutes in to the second attempt of mindless button bashing that I realised what was going on and it was very easy to solve.
In my opinion however silly block shifting puzzles really have no place in a RPG, or is this some traditional console thing?
