Nice music, plot and graphics but game is strongly disbalanced not in terms of energy only, but in terms of berries and experience as well. Also that's unfair to be able to buy new slots for gems whenever you want, but for coins with higher level only. Pet's clues are pointless: it may highlight a block behind the closed door but not where to find a key, what's the point? Also you usually get 5 clues but if there are less than 5 blocks left on a stage - you won't have the rest elsewhere..
