5 stars: Super cute. Super fun. Not really challenging, but sweet and relaxing. Lots of different characters to meet. Which is unusual in this type of game.
4 stars: I really loved playing this game until I got up to the higher levels then it gets too hard. I never earn enough stars to upgrade the characters and when I do the challenges to upgrade are impossible to pass. I refuse to buy boosters for any games so I just stopped playing and uninstalled. Please update the game to make it a little easier, it doesn't have to be easy, just not impossible!
4 stars: overall its a pretty good game, its addictive, the story and the characters are cute as hell, and microtransactions are hardly necessary. although, the app is a little buggy in some parts and there are some barriers that require you to log in to facebook and invite friends to pass them. However, you can just pay with the normal currency coins to pass anyway.
3 stars: Great combination of medium and hard difficulties level with various puzzling types. Found several times once passing level 50 so on, when opening the app, it can either black out or frozen. Once it had opened the level I was in and energy has been placed, it kicked me out, so I lost one energy in vain.
3 stars: I absolutely love this game and have played it nearly constantly for several months now. Somewhere, about two-three events back, the loading time for the game became incredibly... long. I deleted and reinstalled it and it's better, but...
