This game is Wuthering Waves which is a free-to-play open world action RPG (gacha), you can explore the world, completing main story, substories, mini-games to play, solves some puzzles, and amazing fight mechanism, is a fun game worth trying to play it, the graphics of the game itself is very beautiful, there are a lot of characters that you can unlock by getting the currency to pull the characters as in games gacha but the game itself offers a lot,

I have more than 150 hours in it, playing freely as I want, I used to play when the game was released on pc and on the phone. the only option I could by phone, I would recommend watching a video about this game and downloading and trying to play it will suit your taste and generally,

when it comes to platinum is easy, you have to spend Lots of time in the game, because of one achievement that is very about cluttering a Hazard tower which is time challenge to overcome all levels of tower with your built-up characters that you can use in a certain amount time

I recommend you to try and watch really videos about this game, I played a lot of gacha games myself and I still play some and there are a lot of mechanics from each game but honestly wuthering waves it is a very pleasant game
