User Reviews
pretty ok game. i think it's fun, but the character designs are personally not for me. some of them are absolutely horrendous, some of them are ok, and some i am actually very fond of. unfortunately, i have spent money, little around $8 usd, nothing crazy; but i do think this game could profit to be more f2p friendly. and i have absolutely no idea how to build characters or anything, a build guide and ui fixes.
This game feels like it was ai generated, but that could just be a bad translation, the store makes no sense, the conversations make no sense, all the characters are just thirst traps, you get free stuff when you start the game but guess what you need to progress like 4 areas to even you the free draws this gacha game gives you. feels like a ripoff of arknights, characters need complete redesign.
It feels pretty fun, so far! I'm still too early to make any real judgements about the game, but it feels good enough to pick up SSR and even UR units. But since the current meta seems to be MR units, time will tell how progress later feels! At least for new players, it feels pretty easy to get into, but still has a measure of strategic element!
the game has a lot of inconsistent UI elements were they're present in some spots and missing in others. The auto fast forward on dialogue means if you do care about the story you constantly have to turn the feature off. There is an over cluttering with the UI that makes it hard to understand on a phone, perhaps it is better on a pc or tablet but I didn't check. The translation is really off giving an amateur feel. good art but basic auto battler gameplay. recommend for art and generous gacha.
