I like this game n don't mind all of the hidden games (altho i do hate the foggy one it's too difficult n makes me anxious lol), but in general at least i don't have to spend money to pass. But i wish the reward is a little higher, only 5 stars each game (7 & 10 for hard level, but rare) but it costs >20 stars to pass one mission, with some unnecessary missions wasting my stars and i can only play max 6 games before my energy filled... Waiting makes it less interesting n easier to get bored
