Actually I love it cos there are grinding and levelin This game sucks I've spend my money to this game and still didn't get the needs of Cryptons numbers, will need spend money for boosting your Cryptons then collect some Cryptons but it doesn't make it more because it needs Ten Thousand Cryptons for one GUBI that wasting your time and money for nothing because it cannot take it thousand of Cryptons for only 1&2 boosters. But, if you always bought booster. Be smart, if you guys spend your money.
