Good comments but about this game we should have like an update for having different characters,or having missions/challenges/puzzles but also so that there is different areas and new bosses, but about the characters then maybe should be so in every area/boss you unlock the character ,but also so you can change the difficult/new units and legendary units ,but also so that you can use gold to upgrade weapons,armors and rings ,hope you all enjoyed my comment and i hope all of you agree with me. have a nice day thanks for reading my comment. :)
