I didn't have a problem with the instructions myself. The game was very intuitive for me, so I barely looked at the instructions. It's so relaxing but makes me think too! I've had the box bug as well. It first showed up on 2-3 for me.
Little bit of a problem with pieces sticking together. I moved a part of the puzzle I had solved to the side except a couple random pieces were "stuck" to it and ended up off the screen. I couldn't solves the puzzle because the pieces I needed were permanently hidden off screen.
did you try pressing 1 or 2?? or do you mean I should have more skins?
