A very interesting and atmospheric visual novel with unique characters. Considering it's free, it's a great game that's definitely worth spending a few hours on.
a bit cliché, but very cute. gave me an existential crisis and a soft spot for urshu
Genuinely really well done, I really enjoyed my time with this one! All the characters are interesting and likeable, but flawed. The designs are great, and it's fun finding the spirals on everyone. The VAs all did a fantastic job, too. I'm hard-pressed to pick a favorite character, tbh. I really love them all, and it's fun seeing Vivi's dynamics with everyone. Love her sense of humor, also! Surprising amount of variation in scenes and dialogue, depending on whom you hang out with and in what order—not to mention the affection and decay mechanics!
