As far as I know, this game is made by unity3d (2018.4.23f1) and it is an Android mobile game.
It's 3D models and illustrations are really exquisite. I really want to rip its models from this game's assets but I came out fruitless after using AssetStudio, AssetsBundleExtractor, disunity etc..
I do hope someone nice can help me figure this out!!
Thanks!!
And here are some samples from this game (2MB)
