This game is worse. I mailed them regarding Challenge stage. I did 8 mail but they didn't reply. Reply one mail with stupid answer. I am stuck in one stage since 2 years and i am unable to clear it. So I need that stage hero list, but they are not sending it. Noone ever clear that stage, still they are not giving it. I know this game is stupid because 7-6 trial 3 stage is extremely tuf. But this game operators are most stupid because they think giving one stage hero list means revealing all.
