I want the revise my rating back to five stars! As it turned out, the few things I complained about were not a big deal. Yes, in more than one game the total of the negative squares were not equal to the number of positive squares. But what I didn't realize was that once you completely clear the board of, say the negative squares, you get the "winner" screen even though one or more of the blue positive squares remain. The other complaint I had was that the game often "grayed out" which prevented me from going any further. But I discovered this only happens when I hit the "back arrow" to try again but don't give the game adequate time to reset. Instead, I would IMMEDIATELY try making a new move which turned out to be the problem. This has to be one of the most fun games I've ever played and the hope to see additional levels real soon. I'm not a big game player so coming from me that's really good! 😎
