Who is Yunyun? For the lost, she is the vision. For the hungry, she is the chef. For the thirsty, she is water. If Yunyun thinks, I agree. If Yunyun SENDS, I RECEIVE. If Yunyun has a milion fans, I am one of them. If Yunyun has ten fans, I am one of them. If Yunyun has only one fan, that is me. If Yunyun has no fans, I no longer exist on this earth. If the whole world is against Yunyun, I am against the whole world. Until the last single bit of Denpa received, I will, love Yunyun.
I'm making this review from the perspective a person who never really played rhytm games and who's not the target audience (I'm not familiar with most of the songs and I never played denpa games). Initially I started playing this game as a fan of the other game from the same studio - Needy Streamer Overload, plus I really liked it artstyle, OST and general vibe. And the game still delivers in this regard, it's very nice to look at and hear. Same goes for the rhytm part: it's simple, but super fun. I'd say it's kind of addictive. As a total beginner, I also appreciated the accesibility of Yunyun Syndrome and the fact that you have tools to skip rhytm parts/make grindy parts easier (I didn't use it, but still, nice to have a feature for those who just want to see the plot). I also liked the choise of tracks - again, I know nothing about them, but they're catchy, and I liked playing them as a non-fan of denpa. And plot... Well, it exists. That's my main criticism of the game - it's not very well paced, and you basically get plot thrown at you in the beginning and plot thrown at you in some endings. And it's not even subtle - you don't piece together Qtie's story from little details, you straight up get told what happened and what is her situation (but I liked the Qtie logic part! I feel like it was a good way to show us her mindset) Also, there's a sort of bait and switch in the first part of the game, and it felt... not very well executed, I guess. You don't get pleasantly surprised, you mostly just ask yourself "Is that it?". The ending was also kind of unclear to me - there's a message about self-love, but I weirdly don't know enough about Qtie and don't connect to her enough to understand it. I also really disliked how most of the mechanics of the game are used only once and then forgotten. It's just... why put them in the game in the first place? Why not use them somewhere else? Also, the game is grindy. It wasn't as bad for me, because I was at least learning the rhytm genre, but sometimes it did feel like a slog. Especially when the main gameplay loop is... kind of meh. Maybe it's me, but minor endings and cospiracies were boring, and I just skipped them most of the time. It honestly feels like the plot and additional mechanics were either rushed or just tacked on the rhytm part. Maybe the game had to stay in development a bit more, I don't know. All in all, I'd still recommend Yunyun Syndrome, especially to people that want to get into the rhytm genre - and especially if it's someone like me who didn't really feel drawn to Osu-like games. Or if you like cute characters - Qtie and Yun-Yun are very endearing. Just don't expect much from the plot and the message of the game.
It's fine. The art is beautiful, the voice acting good, and the rhythm game is fun albeit forgiving to a fault. Still, the harder difficulty will be enough for tryhards like me to sink their teeth into. The one problem is that the game very much wants you to play it for the story, but the story is pretty shallow. Lots of interesting concepts which don't get explored enough for the ending to be satisfying. The ending itself leads to a confused (not confusing: confused) message about mental health -- though I imagine it might resonate more with a japanese audience due to the stigma around mental health. Accepting that you're mentally ill and that it doesn't make you irredeemable trash is a big enough step. Also, the game could really use with having less of the conspiracy endings. They're very repetitious and most of them don't really achieve anything in regards to character exploration or anything. some of them are plain funny which is fine, I'm especially fond of the fourth wall breaking ones, but a lot of them could've been one off jokes that didn't require literal grinding for lol.
Thanks to the developers for creating a game that mirrors my and many other peoples lives. The rhythm game is very well made. As a rhythm gamer, it's the first time I enjoyed a rhythm game in 3 years, all the songs are amazing, effects, interface, impact from button press, accuracy, everything is incredible! Remember about issues with the English localization, they exist, and devs are actively fixing them, as well as other bugs in the game, it's truly wonderful to see how much devs care about their project. The animations in the game are simply awesome, my eyes are addicted to them! I won't say much about the characters and plot, it can catch any person in own way. Rim de Lacent!
