This game has the best riddles out out of all other similar games I've ever played. It can be hard sometimes, but never impossible. You will find yourself having better skills in observation puzzle-solving the more you play. The only problem I've had is the fact that it can sometimes glitch. When I tap on an item, nothing budge. I thought it wasn't important until I got stuck and use my star for hints only to found out about the item. This is truly devastating, but I'm glad it's not frequent.
