could be good but...........
1.its not bug free,sometimes you cant attack and others you cant even press buttons.
2.its impossible,u have 50 health he has 2000 and you cant inflict sufficent damage to win.
3.you dont have enough money to start with and as i said no way to get past the first guy.
Well, I'll give you one point. I DID forget to mention you're supposed to level up before fighting the king.
DUH!!!! There's the Arena button on the right side of the screen.
I don't know what you mean by "sometimes you can't attack" I hope you realise this is a TURN BASED BATTLE SYSTEM, which means you have to wait for your turn to come around again.
