I got burnout from this game I quit during Tiphera banner.What is the point of grinding and resetting to get the best epiphany if the dev nerf them later on. Also the story needs a rework like why the MC is so dumb he is the Captain lol, bet we get a better story if you haven't bullied off the MAIN writer.
★★★★ Tony Leo 5/8/2026 v1.0.268
Horrible rates, and censorship.
★★★★ Dave 5/6/2026
I'm taking back what I said. I love this game. I love how it strips you of freedom and forces you to watch the screen. I love how it is more of a painful job than a respite in your free time. And, I love the anniversary event. I love it so much that I uninstalled this game today. Should a normal person spend hard-earned money only to not get what he wants for that? P.S. I'm never touching any korean games again, thanks to this new update.

stingy when it comes to rewards, the heidemarie ads got the best of me.

★★★★ InCrZ 5/4/2026 v1.0.277
game has been awsome but recently came across a bug that won't save my character loadouts lost 2 awsome loadouts contacted devs they dont care they want me to waste another 30mins or a hr to see if its stil persisting after 3rd try....
★★★★ Ashari T 5/4/2026 v1.0.277
I have been trying to login for days now, it stays on the main screen that says patching but the game never loads no matter how long I wait. I have cleared cache, uninstalled and installed the game, and I even restarted the whole phone. Horrible experience, which is a shame cause the game is quite good.
★★★★ Dark Mourne 5/4/2026 v1.0.203
I enjoyed the game for awhile. Insane luck to build decks and very boring long sessions with cheap deaths. Not enough resources to pull character's and partners. Very expensive store so not worth paying. Time to move on.
★★★★ ᴋᴇɪᴛᴀ 5/4/2026
Never won a single 50/50 on this game.. i always go hard pity and losing to the shttiest characters ever. i feel like all my timw invested in this game wasnt appreciated. i feel disrespected and feel like the game doesnt actually want me to play it at all. now i stopped my spending and just treat the game as a daily chore.. didint even bother for sereniel cuz ill know ill lost the 50/50 again. UPDATE: Got back to heme banner and lost 50/50 again. Officially quitting i js cant.
★★★★ Botan Bra 5/4/2026
Repetitive is it's name.
★★★★ james William 5/4/2026 v1.0.277
Even in 3rd season, this game is still failing. the new mode sortie forces the use of a very small pool of units to succeed. it is no difference from all the previous chaos modes. the devs still fail to make the game so that any team can be used.
★★★★ Timmy Krouch 5/3/2026 v1.0.277
This game is way too grindy and not in a fun way but a repetitive way. unlike slay the spire where there's several build options chaos zero nightmare shoe horns you into specific builds if you want to beat the gimmicky bosses for events. Worse yet stamina is non existent, chaos gets boring fast and they limit you on quick sweeps. Just allow the players to quick sweep however much they want or reduce the time you need to spend trying to get through a chaos for the 100th time. Annoying game.
★★★★ Exc Gam 5/2/2026
boringggggggg
★★★★ AAN TRUEMAN 5/2/2026
i think the game is very slow and very clunky when choosing a card even on the pc The same problem, characters are odd not very unique or a story to attach to the character.
★★★★ Arxtd84 5/2/2026 v1.0.277
my y700 have connetion unstable when play this game every damn minutes

why remove the x2 x3 speed on chaos?? what a bunch of clowns 👍
★★★★ Neo Nahid 5/1/2026 v1.0.203
More male characters please 😢
★★★★ Matt Rainforth 4/30/2026 v1.0.277
Absolutely diabolical to be running 2 different rate up units at the same time, both Heidemarie and Diana. I confused Diana's banner with Heidemarie's banner. Devastated that I wasted my pulls on a dupe Diana. You guys should separate the rate up units and rate up partners properly as the UI was so confusing with 9 different banners and you have to scroll to see the others. Literally can't see Heidemarie's banner as Diana's banner is SELECTED TO DISPLAY BY DEFAULT. What the hell is this?!
★★★★ E M 4/30/2026 v1.0.277
Cant start the game. After selecting the server and language, I get a black screen. Redowloading the game didnt help.
★★★★ al f 4/30/2026 v1.0.277
why you guys always deleting google account? my epic7 and czn account gone. if you're gonna keep deleting google login account, just don't keep the option to log in with google.
★★★★ HiImYolo 4/29/2026
this game had alot of potential but they dropped the ball heavily when they forgot male characters exist.
★★★★★ Master Assassin 5/5/2026

a whole lot going on and none of its very fun. pretty typical gatcha confusing and meaningless dialogue and random characters. the memory system is interesting but otherwise I can't find the fun here. spend more time navigating menus than actually doing anything.
★★★★★ Vision Zarako 5/4/2026 v1.0.277
I think the storytelling post apocalyptic worlds is cool but this story is horrendous. The RNG is what you'd except (not great), I do think the concept of card battling as a gacha feels weird but it works I guess. This game is also way too RNG in gameplay as well as epiphanies. I think we also need an AP save mechanic so some of our AP can be stored at least. Also, why is the captain so useless?! This MC has time powers that he can't utilize and it makes zero sense. Literal baby wrote this story
★★★★★ Ridho Sani 5/3/2026 v1.0.277
after half-anniv update i can't update the game always stuck at verifying update
★★★★★ Garrick Borrough 5/3/2026 v1.0.277
Smilegate, why would I play this over Nikke if you're gonna cut back on males? Game is quite beautiful, but lacks a lot of direction. Honestly. Just make it a complete offline game, $30 for about 30-40 hours with all characters and story currently. Girls only? They only make money if you actually have something. You do NOT have it. Despite e7, I'm here just for Hugo. I'd be an active minnow, but still do my part as a player/fan if the devs actually liked their game.
★★★★★ Dario “Howl” Erdeši 5/1/2026 v1.0.277
Gameplay is good,story is ok(morimens is better imho) however the currency is mostly paywalled,Barely any playable male chars,if you like fan service then it's great for you. Relying on rng to unlock battle missions ist stupid af tho and as mentioned before the lack of playable male chars is just a turn off and the MC(you) is locked to female... I'd give it a 3* rating if they'd respected all users and not just hyper focused on it being a gooner fan service collector
★★★★★ Ethan Chavez 4/30/2026 v1.0.238
I want to give this a great review, but drop rates are just so bad and the shared pool with partners makes it even worse. Runs take way too long and there's no way to automate combat / speed it up most of the time. I would usually do like 1 run (you are locked in until it's complete, which is also frustrating) which would make progress really slow. Otherwise, I would just do a few small tasks on login then not play for the rest of the day.
