I always confuse my character with the other characters in my party especially when we are all attacking the same monster :/ I hope they would make an update so that we can easily recognized our character
You can buy energy through mobile if you don't have any credit cards or your parents don't let you to borrow theirs.. I buy them through mobile all the time, not really that expensive.. I don't know for other countries though..
U can beat the robot boss by using the girl as a healer and the boy as an attacker.. Just keep using the legend technique with the soul eater sword with the boy... if both of u are both heavily damage... use the heal more technique.. and also I dont let their hp go under 6000 hp..
