Gameplay: this is not a game that played itself like others out there. You have to win the battle manually, so you are really using your brain a bit and actually playing the game. To fully enjoy all the game mechanism and features, you need to play for a while (Chapter 2, Stage 2). Some features also not mentioned in tutorial, so you have to figure it out yourself. The character roster isn't much at the moment but then considering gacha rate to pull new character (12%), it is fair enough.
Graphics: no graphics setting (current build), so some old devices might get low fps or not be able to play. Character design is very good, personally like the concept.
Sound: nothing special here. There is no character voice in current state of the game so it is quite a downside. Prolly something to do with dev's cost or agreement if they trying to add actual voice actors in game.
Storyline: basically multiverse on disney universe. Never really follow the plot. I leave this section on neutral score (3/5)
Value: it is an actual game. Many 'mobile games' nowadays is not an actual game because the game play itself with just press of one button. As for current game state, there is not much to do beside story, grind stage and events. It will be better to add co op in the future.
