Somehow, I overlooked this game, but just stumbled upon it. Yes, there are some pop-ups, but not as intrusive as more recent games. I have only played the Demo, but think it is pretty darned good. I'm going to see how I like Emberwing next, another one I missed somehow, and possibly pick them up in the next Two-for-One. Both games are pretty simple for my taste, no big challenges, even to figuring out where to go next or what to do. Everything is obvious. But they are good for whiling away a few rainy hours.
