the worldbuilding is pretty interesting, but the character designs and storylines in this game feel a bit too similar to other yuzusoft titles. nanami’s character is really well written though, and her route as the imouto is just perfect and cute, which kinda makes up for the repetitive feel of the plots and characters. but after finishing nanami’s route, i didn’t really feel like going through the others anymore. ayase is voiced by tanezaki atsumi, and that gave me a bit of drive to finish her route… i’d give it a mid rating, with a small bonus for the slight tsundere vibe. chisaki is voiced by kanako, and i really like that va’s voice, so personal thumbs up from me. the other characters just didn’t grab me much though. overall, riddle joker is pretty average… aside from nanami’s route, the script didn’t really wow me rank:6/10

Key takeaways from the game (for me) - Nanami & Mayu best characters imo - Cute chibi - first in my bloodline to ever play such a life changing game Overall, even though I still need to complete a few other character routes if u enjoyed other yuzusoft games u will most likely find urself enjoying this game. 😁
