ANONYMOUS Level 3 of the demo does not work properly. If you select one of the Pegits, its arrows light up, but if you change your mind and then select a different one, the firsts arrows stay lit making the puzzle hard to see. As is, puzzle three is unsolvable. When you try to select the pegit in the bottom left, all you get is a red box around it and it will not move.
As is, with only three demo levels, one of which doesn't work properly, I'm unimpressed.
