I really enjoyed the puzzle design in this game. There was a moment in one of them where I was able to reason out exactly what I needed to do and was able to execute it. The graphics work for the game and the background music is as unintrusive as one could hope for. One difficulty I had with the controls was that worry of getting near pixel-perfect in movement because it was easy to accidently go over or hang over just a little and it affected the ability to push things effectively. I had to be very careful in my movement.
