Not a God-tier game, but...

The game itself is cute, charming, and fun. There's enjoyment in pulling for characters/items, but I don't know about the fun of pushing through stages. One thing to say is, this game is a pay-to-win disaster without spending money. Mythic skills are incredibly hard to get, and getting Mythic runes is practically impossible for free-to-play players. Half of the event rewards are designed for paying players. The gacha rates are also an issue, and even mounts significantly boost attack power, making it very difficult to progress beyond Hero tier without spending money. I recommend playing with these factors in mind.
