no real storyline, but still entertaining to play in between other game hyperfocus sessions. It’s also pretty great for waiting rooms or taxi rides. I believe it requires a data connection so flights are off the table. The animation is cute and I enjoy the art style. It has some pretty loud sound effects, so earbuds or turning your device down is highly recommended while in public settings. Leveling your heroes after 100-120 is a tad difficult as it’s Gacha based and the really good ones are rare drops. There are no controls or anything like that so no virtual button mashing required. If you’re an achievement gremlin like myself, there are plenty of opportunities to scratch that achievement itch!
