I very much enjoy the game, the Gacha isn't too much and the grind isn't blocking the enjoyment of the game (which did happen multiple times with Genshin Impact). The gameplay is very reminiscent to a turn-based JRPG which I really do enjoy.
It has very good looking animations, a nice anime aesthetic, fun and intuitive combat and great music, I'm pretty happy with it and I haven't used a single cent on it.
The story seems interesting and the characters work very well in their settings and missions making the narrative very enjoyable.
That being said, the grinding IS there and during some events it likes to creep its head out; still, I don't find it AS invasive as Genshin's so that's good.
