Actualy the game is great game ans puzzle so much fun, but why i put 1 star? Here the thing, the unlock a chapter you need a key wich i need more time to get get a key. But i dont mind to waiting to gey key but more anoying is when i unlock a chapter i need to WATCH STUPID ADS even i have a KEY. So why i need to waiting to get a key (2 hours) instead watching ads???
