The cards are beautiful in this game and I have been very lucky to get four 4*s with my free pulls and free tickets from the beginners logins. The live stage/clubs are very nice too and I'm impressed that having so many cut ins and sfx doesn't make my phone lag at all! The only downside is the sfx are so bright and distracting it makes it hard to play the game so I have them all turned off (｡>﹏<) I think if I got more used to playing with them this wouldn't be a problem.
I'm happy there's a wide variety of music in this game like originals and covers and fan music and even bgms from games! It's really refreshing to be able to play something different. I don't really have a fav song of the originals though, maybe it's because I don't know the charas/groups very well yet, but none of the originals really stand out to me.
The gameplay is really good and not laggy for me even with all the sfx, sometimes playing with others filling a waiting room can take a while but that's not the games fault. I wonder how many players there are? Or if it is just that live rooms have problems connecting people. The game is very user friendly that you can have as many kinds of notes as you want on auto even if you're doing an event or playing with others, it makes the game so much easier and people can just play the parts that they want to play. I love the medley lives I think they are so fun.
I've seen a lot of reviews talk about how unfair the gacha is or how there are lots of limited gachas compared to permanent and I hope they add more permanent cards soon, since I don't have any fav charas yet limited gachas make it really hard to know who to pull for.
I haven't read much story yet and I don't know lots about the characters but the stories don't look bad, they are like regular stories you'd find in any other game.
I think this game is worth trying if you like rhythm games because the gameplay is a very unique experience.
