The game is entertaining although battles can get repetitive after a while. However, the biggest issue are the bugs in this game. Constant and random crashes occur every few minutes. Either the app will quit without warning or it will stall out or return you to the title screen. Wright Flyer Studios and Bandai Namco are not small indie startups and should be able to devote additional resources to resolve these issues. The poor gacha rates are just added insult to the buggy app. Edit: Lowered to 1 star. App still crashes (no fix for above) and gacha rates are terrible. Waste of money.
