I've rated the game overall as 3 stars, but I would rate Ryuki's route 4 1/2 stars. Mizuki's route genuinely had me so angry from how it just vomits information on you instead of letting you figure stuff out. There's some clear set up for a threequel that I hope will elaborate on Ryuki because we get no information on him in this game.
This could have been as good of a sequel as VLR was to 999, but it felt like this game was trying to do wayyyy too much. Half the characters could have been removed and it would've been the same.
I HATE BIBI SO MUCH. I HATE HER. She literally makes the entire Mizuki route feel like the shittiest fanfiction. IDGAF abt her twist abt us playing her for half the Mizuki route. THAT TWIST WAS COOL FOR 2 SECONDS AND THEN I GOT REALLY MAD! The Mizuki adoption retcon is stupid and dumb. I honestly thing this game should've been exclusively Ryuki-focused. His character wasn't even fully fleshed out yet he was one of the most interesting characters to come out of the heap of shit characters this game has. Kizuna and Lien should have just been removed, they do nothing. Riichi Chieda was just a nothing red herring. Tearer's identity pisses me off. I don't know what happened here but I wanna cry.
I enjoyed playing the game, but I was genuinely enraged playing the last 10 hours. I felt like I was playing a fanfiction.
It made me so mad this is the longest review I've ever written for anything.

The 3rd Class Cabin bonus somnium made me really happy though 10/10.
