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.

The gacha is too expensive but the rougelike gameplay loop is highly replayable and fun. Especially sortie mode which takes it up to 11.
