This game is unexpectedly fun.

The art is pretty nice, all cute girls and nice background.
The music is also calming, and quite fun to hear.
The story is pretty simple and straightforward, don't expect much twist.

Gameplay:
- You can skip (more than 3x speed) and auto battle, which reducing clicks and battle time. This feature really needed to be implemented to all RPG.
- You can save anywhere in the dungeon as well, which makes it really easy to exit the game anytime.
- Battle system is just a turn based with minimum animation, so it is really easy to learn how to play.
- It is also surprisingly supports controller. I play with Xbox controller.
- There are 30 level of dungeons, 27 stories + 3 for addition level after beating the story. Some floors have a fun gimmick, if you want to spend less time, you can also check the community guides which helps me saved me a lot of time.

Clearing the story with abyss difficulty also unlock the achievement for clearing the story with hard difficulty, which is nice. I thought I had to restart the game with hard difficulty as well.

The last achievement I need to unlock is defeat 5000 enemies, and I finished all the content at around 2600 enemies. Took me another 10 hours to just grind until 5000 enemies.
