I found this to be a pretty good game. I did not really care for how difficult it got. Of course, it might not have interested me that much to begin with. I guess it was a bit bland. I still found it pretty creative, though. I always like new things.
There was always something going on. It was just more of the same. The music was quite nice. It did get more interesting as it went on. It wasn't quite something I would recommend, but good.
