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.
