I've played this game for months now and enjoyed it, buying items, playing daily but it still has unresolved issues the devs have not fixed, giving them a 1-star review is a desperate attempt to wake them up, in fact, everyone should leave them a 1-star review to force them to do something about the problems in this game which are numerous, but go to their Discord server to see them. Levelling heroes requires a ridiculous amount of resources and money, cashed-up whales now ruined the game, etc.
