Graphic : This game has probably the best graphic among the games that I have played this year. Designs are beautifully balanced between being cool and of 'fan service'. However, there are some characters that has some glossiness that's often shown in AI arts. I cannot say for certain that it is AI generated but some characters do look kinda off.
It also supports characters mouth movement when they speak, and it fits the dialogue pretty well.
However, battle uses chibi models, which some people may not like.
Soundtracks / V.A. : It has really nice, calming soundtracks that does help you get immersed into the game. Best part was that it's not deafeningly loud like most of the other games are these days.
Game is fully voiced, including MC. Most of the chatacters have quite well matching voice, but I'm not really digging MC's voice. His voice itself isn't bad, but it's kind of too monotone.
Gameplay : It is very much like auto battler with large grid, where you place up to 8 characters with 4 different classes.
However, unlike auto battler, you do have to tactically place each character for them to be able to do their job.
Characters stats are heavily dependent by their class, such as defenders having extremely high def and HP, but horribly low atk, while some attakers have extremely high atk, but menacingly low def/HP. So you have to carefully place each character into right position, or you may even lose to weak enemies.
