Up Left Out comes from Maciej Targoni. Any time I see his name, I know the game is going to be artistically and intellectually pleasing.
There are 51 levels. I solved them in about 1.5 hours. Not too hard. One particular element, which I won't mention its nature, is really cool.  Well worth $.99. Keep up the good work Maciej.
