NSO has a great aesthetic and music! Ame/Angel both have very cute designs and it has a fun vibe!
Unfortunately, to really get into the story you have to go through multiple endings and it can get a bit tedious. However, I loved the addition of fan content and collecting the pieces of art! I found it super sweet and endearing.
All in all a game I enjoyed playing, I have multiple friends much more in the target audience who adore this game and I can understand why. Maybe one day I will go back to finish every ending but I won't be in a hurry to complete it.
