Its super fun and i love the visual. But the balance is off. Its super grindy, and mana bomb and mini bosses upgrades is a debuf. Mana bomb eats energy and does less for it while it takes the same time to finish the animation as it would have taken to mine it yourself, giving no benefit. And minibosses just soften you up before the boss. Especially emerald 2, snakes just spam 40% of your hp.
I want to love it, but this game bites. Its easier to to restart and skip the debuff upgrades untill later on when maybe the super grindy battle tree is unlocked more.
