5/5 Gameplay loop is incredibly fun and addictive. Endless character and card combos to discover… high amounts of replay value. Devs have been attentive and generous with rewards. Currently my favourite game. Writing this as mainly a PC player as well.

I think the game mechanics feel fresh for someone who has played so many Gacha games. Overall I don’t have any complaints the game runs smoothy the character designs are good. The animation and voice acting for the characters are solid. Overall I think this game will stick with me for quite some time.

I have no issue with the gameplay. It’s just that this game used to be a semi-horror game with very promising character designs, even including furries. But now it’s become yet another Browndust 2 where every female character is designed to show off their huge bazongas and their thicc thighs. The devs really took away the unique feel the game once had.
