Not Bad

I downloaded it for the exploration quests and didn't have high expectations, but once you understand the game rules, it's surprisingly fun. However, if PVP isn't your thing, it might be boring since there's no auto-battle. And when you get characters? Or cards? Anyway, you get blue and purple ones quickly, so upgrading the blue ones first is beneficial for hidden quests and the game overall. Upgrading requires a lot of gold. I upgraded the green ones too, and now it's hard to proceed with upgrades at 102%.
