UPDATE 1/1/20: Where are all the paid levels I thought I was buying? I love this game, originally gave it 5 stars, and thought it was one of the best I’ve played, but had to lower my rating a little after paying for more levels. I discovered it was just a few more levels and played most of them in about 30 minutes. Then, when I returned to play the rest, I couldn’t figure out which ones had already been completed and had to open each level to see if it looked familiar. Maybe they mark the levels that you already played, but I couldn’t find an indicator. I still think it’s an excellent game, but the paid levels really need to be longer.
ORIGINAL 5-STAR RATING (with revisions): I almost never give 5-star ratings. This game joins the ranks of The Room, The Birdcage, Da Vinci, and a few others. Great graphics, creative, original and clever design, music that’s not annoying; it’s challenging, but not so difficult that gameplay slows down and gets boring. (It’s an art form to design a well-paced game that sustains interest.) There is a logical sequence to the gameplay, so if you have good reasoning kills, you don’t need hints. The free levels are enough to pique your interest, leave you wanting more, and they don’t have so many ads that you can’t focus on evaluating the game. Additional levels are appropriately priced. I’m going to pay for more because IT’S A WINNER!
