Amazing cast of characters, great music for a mobile game, and a very interesting story. I find that the combat had some depth and the different mechanics that alot of the bosses had were fun to learn. For a gacha game it really surprised me with the amount of work and care the developers gave. Its unfortunate the game ended service.
My second gacha game, after Fire Emblem Heroes. It was very generous with the amount of free summons and content available, but it was also extremely grindy. I didn't care much for the gameplay itself (and how it performed on mobile), but I did enjoy building characters and collecting collectibles and I have fond memories playing this in multiplayer. The devs put so much work into the events and quality of life improvements that it's sad to see the game shut down. I hope Nintendo and Cygames use the IP again one day, because I like the characters.

I'm sad I never got to play this in earnest. I was collecting Gacha stuff for when I would finally have the chance to play this game properly, only for them to just tell me it was shutting services down. It looked like an incredibility neat game, and from what very little I played, I could tell it was quality. Hopefully some day someone can come and save this game.
