Too many adverts for me. Got bored and fed up with them by the 3rd room. Sorry. It seems like it could be a great game otherwise. I don't mind watching ads, to earn hints or upgrade etc. But for my personal patience, the ads when going to the next screen or the last screen, was too much. Apart from that, the first puzzles were great. The search was difficult, but probably get better hang of it as I learned the game. Worth a try if you are more patient than me
