In terms of graphics they are amazing (see the official screenshots below) and there also a lot of small details like you can see your portrait art changes according to anything that you have picked up. Some CG events even have some animations. In this game there are no battles but chasing.
Generally games that are solely/mostly made by artist(s) have so-so gameplay, intentionally or not, and unfortunately this game is one of them.
