The game is a gooner game ngl because of the massive fan service. If we put the gooner element to the side, this game offers a unique mechanic in the core gameplay of the game. With many potential decks and build you can do, it really offers a variety of gameplay. The game is also quite generous with the rewards. I have 5 5* as of now and none of them are early pity. The only complain that i have is the endgame and events seems repetitive as of now. Hopefully devs will add new modes and events that offers something refreshing and new QOL as well.

I’m surprised how well made this game is. From the characters and all the way to the game’s UI are well created. The gameplay is smooth with a hint of challenge. I love the concept of the whole game. Combining RPG and anime with sci-fi horror. The ‘mental breakdown’ occurrence in battle is smart. Every single battle options are well put. There are a lot of effort, love, and details being put in this game. I hope this game will thrive because I love the overall gameplay.

First of all to the developers, I’m loving the game and all. Love the gameplay, battle system, character design, story and lore. But… omg the storytelling and cutscenes is just too much, sometimes the dialogue between characters going back and forth is just too long. But still would recommend everyone to give the game a try. Much better than Honkai Star Rails

The game is 10/10 so far, but there’s one bug that affects my gaming experience. Sometimes when I pull down the notification bar while playing CZN, it will quit and restart for some reason. This is the one and only issue I faced with so far. Keep up the good work guys, MUCH LOVE
