It ran smoothly for me, and I loooove the concept and the way it plays. I felt like money was sort of tight though, even with going back and playing the earlier levels with advanced characters. Definitely something I would want to play through.
The directions are not clear, when you first start out, and the layout in help is just difficult. It was very difficult to get a feel for what I was even supposed to be doing, I didn't know where I could get guys from etc., when I started. Very mediocre. Needs to be cleaned up, made more user-friendly.
I wish there were a way to change your mind after you click on one of the extras but then don't mean to use it. It gets used as soon as you click it, rather than when you click on a tile, to use it. Also, a "reset" option would be spiffy, or a way to save your progress at a certain level, to come back to would be great.
