Lost my acc

After not logging in for a week, i decided to finally logged in back in the game and suddenly my acc and all my progress was gone after this new update

Segunda review ;)

Eu amo esse jogo, mesmo tendo uma arte simples é muito bem feita. O ponto principal q eu gosto tanto dele é a sua mecânica, eu gosto muito dos diferentes monstros e oq me surpreende é a diversidade gigantesca de eventos. Um jogo extremamente viciante e que eu não acho q vou nunca parar de jogar

Recommendation

Great game just that the in app purchases are too expensive. What if there is a discount especially on christmas

Actual masterpiece

This game has to be one of the most underrated games i ever played it is actually insane, you cannot win though, it’s impossible.
