Story- 6/10. Coming into this as a fan of the Nikki franchise, I am unimpressed. I've only finished two chapters (excluding how far I got in CB2, but it doesn't really seem like they changed anything anyways), but so far I am extremely bored by the story. I don't know if it's the characters, the constant cutscenes for no reason, the soulless facial expressions, I'm not sure. The story doesn't do it for me.
Graphics- 10/10. Extremely high quality graphics. No gripes whatsoever, everything in the game looks absolutely beautiful.
UI/Optimizations- 8/10. The UI is fine. As far as optimizations go, I've had zero issues personally (besides a glitch in the story cutscene where two characters were standing through chairs and they were supposed to be sitting, which also existed in the beta. devs already don't listen), but I'm also on a pretty high quality rig (4070 Super, 32GB ram, AMD R9 7900X) and I know when I played CB2 on my phone it looked terrible. In CB2 I did also (in every survey, might I add) request they add a favorite button for clothing pieces to be able to sort through clothing pieces I like and don't like, which they still haven't added, which was extremely disappointing.
World Design/Music- 10/10. The world design is incredible, and so is the music. I wish there was more put forward as far as world building goes, as this game doesn't exactly build from the same storyline for Miraland as the two previous games, but I've found some info from investigating books in the overworld, so I guess it's fine.
Clothing Design - 10/10. Usually this is my character design category, but since the gacha isn't characters, it's now clothing design! Which of course is amazing, huge quality improvement from both previous installments of the franchise
