The loading every time you enter a menu is annoying but it seems okay so far.

Game isn't perfect, but the optimization is so top tier it needs 5*. And the QoL updates coming to it after a couple of days of release? Amazing. Hope the devs go far, they've shown competence enough to make a successful gacha.

it's laggy when using ultimate skills and between menus, music doesn't go well with the themes, besides that it's all great.
