The combat is very good there's a lot of potential we can dig out from evolving skill mechanism.
The story is quite meh at least from me.
The soundtrack is decent ( TBH i expect a lot since the one who made AG soundtrack is Vanguard studio but i dont know why AG music feels kinda bland for me unlike PGR and Girl Frontline Vanguard did amazing works for those two).
For the gacha system is OK not really that special or F2P you need to skip some character if you want to get the character you want so nothing special.
The optimization is really good there's no stuttering in fps and my phone temperature is quite warm after plyaing for 1 hour which is really good.
The microtransaction is really expensive for coating with minimal vfx and crappy battle pass. I can understand if the games have similar gacha system like pgr/azure lane/PTN i dont mind spending some money in that kind of games but sorry i wont spending on AG at least for now.
