================================
In the long and repetitive dream,
Quicksand constantly pours down.
The compass of destiny starts to tick.
The two wake up and embark on their separate journeys.
On this shore, you emerged from a perilous situation but were exiled to the harsh North Border, struggling to survive.
On the other shore, you found yourself in a maelstrom of power, striving to escape from a cage woven with conspiracies.
No need to bid farewell.
As time perpetually flows forward,
As the two shores will eventually meet,
You will meet each other one day.
So let me start by saying the game is amazing any fan of both anime and warframe should try the game. but for all the good things i could list everything it borrows from warframe or where it innovates on existing ideas, but instead i think its better to adress the fixable faults. Firstly balance for a new dev is quite good but some characters don’t reach the power fantasy level kit randy and some weaker damage dealers could use improvements but small problems easy to fix the bugs at least on mobile can render the game unplayable like lingering effects blocking visibility and blinding the player. however i haven’t seen many of the bugs in awhile so likely fixed and again mobile specific control size and position can’t be changed. But there’s plenty of good the ai companions while stupid are well designed, afk farming viability, absolutely no stamina, cosmetics only gacha, all characters and weapons are free are all stand out to me. however give the story time as it has converted from gacha it needs time to adapt.
Good but..

Been playing for a few days now. Really pretty game has tons of potential but… many issues. First is camera. It keeps zooming in on the character when I fight or need to jump or anything really. Cant see the bad guys your even fighting?! I cant jump because I cant see what I’m trying to jump too! I went into settings and tried adjusting camera settings and it does nothing. All I see if the back of my toons head fighting blind. I use my pinch to zoom out works for a second till I swing my sword or jump its back to her head?! Please fix this. Please put an Option to have it permanently zoomed out switch. Another issue is you will be fighting on a bridge in a factory and many bad monsters zoomed into the head of the toon I end up falling off the bridge and cant get back to the bridge? There’s no unstuck character option anywhere??? It keeps restarting me in the stuck position if I kill myself. #1 game if that was fixed and the camera zoom option was available. As it is now it’s unplayable because you have to fight constantly when doing missions and i cant see what I’m doing and the toon will jump doing these fancy moves which will make you fly off a edge and get stuck lol. It’s bummer tried to go to developers site to submit issue instead of here because wanted to give chance to fix before i review it but there was no options to submit a issue on the website nor through the game itself. Hope you guys fix this so this game can really sing! Ty oh and I’ve played this on iPhone 13 Pro Max and iPad Pro both issues on both devices I’d hate to delete this it has so much potential
My Experience Has Someone With Hand Issues.

I played until arriving at an inn that’s describe as a “Haunted House” and here’s what I stumbled upon. I can’t play games for long periods of time on touch screen mode so I use a controller whenever I can for my hand’s sake. Unfortunately, in the current state of this game, playing with a controller is kind of a hassle. I can’t reload my gun with any of the controller buttons so I constantly had to reload in my fight because I had to empty the magazine entirely. Aiming is the same as shooting, I can’t aim before engaging in battle so I have to shoot if I want to aim. During visual novel type dialogues, I couldn’t continue the next dialogue with any of the controller’s button. It wasn’t until I hit the “Auto” button on the corner with my finger that I was able to continue the dialogue. Then I would go back to the controller only to realize that the only way to continue the dialogue was by hitting the “Auto” button. Also, in visual novel dialogue and cutscenes alike, there would be a constant ticking sound that was very annoying and would get me out of the immersion. For what I’ve seen so far, this game on PC runs pretty good on launch. Unfortunately, I can’t say the same for me in my IPad. I would love to continue playing this game since I’m a huge fan of Warframe, but if I can’t play smoothly with my controller, then I won’t be able to play for long. Hopefully in the next couple of patches, the controller experience will be better along with the dialogue experience as well. I PRAY THIS GAME CONTINUES TO DO GREAT THINGS!!! I HAVE HIGH EXPECTATIONS!
Great game, horrible experience
night, mayor
This game is a great core game. But it is an unplayable burning dumpster fire on mobile. Graphics are throttled down incredibly low even on highest settings. Mobile controls are absolutely unplayable. Somehow though controller support is even worse. Some inputs lock out other inputs (many times you’ll become unable to jump for no reason). Controller will cause the game to crash. Most insane is that tapping L2 even if accidentally locks the entire game up because an item wheel appears and noting can make it go away, blocking ALL other inputs. No fighting, no jumping, no menu access, no pausing, nothing and the devs haven’t done anything about that GAMEBREAKING issue for a month. Not even the ability to remap your own controller buttons. You can’t even access the menu to see a controller mapping screen, it doesn’t exist. It does on pc, but not on mobile. I want to love this game it has a lot good but these developers need to prioritize game breaking bugs and realize how many mobile players they have. I will HAPPILY change my review score when the game feels remotely playable on mobile with a controller. Also, they did a major patch today and now I’m locked out of the game entirely because the game recognizes that there is a new version available at log in but there is no update in the apple App Store. So many L’s
