It is a great game BUT super ridiculous when it comes to beating the games in the journey. It is SUPER EXPENSIVE because you will lose 80% of the time against AI. It cost me almost $13 to beat ONE level, after playing that level for 4 days on the free energy several times a day. Im sorry but I will no longer purchase diamonds or energy. So many times the AI characters instantly beat you In the first or second round even if you have Star cards and skips.
