The games of Kai Werder provide questions, and at the utmost point towards an answer; their attempting to use the limitations of the medium rather than trying to emphasize its latitudes to make a point might not be unique, but is rarely implemented in such a elegant way.
This is a really cool take on Solitaire. One small thing that would be nice is something that tells you how long one halo can be. I initially attempted to put all the pieces together as one halo and realized it was multiple but it wasn't very clear how many pieces made the one halo. I love the music and the colors as well. Such a lovely game.
