The one thing I will preface about playing takt op. Symphony... If you are clueless at all about who the Conductor is, or what anything is referring to, watch the anime that was released. It will give you some history on what you're looking for.
But for the game. The battle system I enjoy. Music selection great, as obviously the music is tied in to classical pieces. Over all, game is rather solid so far aside from what the gacha pull rates are for higher rarity. Depending on the banner, you're looking at about .75% to 1.5% for the 3* pulls.Β There is the guaranteed 3* pull within 75 draws, but still the rate is low.
I do come across the issue where my game screen flickers, but I'm leaving that to be a part of the test build that is currently released, while annoying, it doesn't impeded really on game play. Tends to only happen when switching screens.
Part of this game is interacting with the musicarts, which includes side stories, gifting and increasing your friendship with them.
Otherwise it seems to have a lot of your typical anime gacha parts. Missions, battle pass, item shop, etc.
