This game is excellent! I really enjoyed playing the demo, and am super curious where it goes next.
I LOVE the flat coloring, it's beautiful and stylish with the bright colors and use of shapes. Everyone's hair is so beautiful, and I love the facial expressions! I love the music as well, especially the clubroom song. <3 Seriously listening to it on loop while I write this, its SO GOOD.
I'm not usually into school settings, but this is honestly super cute. I love the interactions with all Aiya's friends, they are all interesting characters in their own right and the dialogue between them is really well done. Aiya herself is darling, and I like the LIs so far (Haru is the best though: seriously, have you seen this gorgeous nerd blush?! <3)
Overall a really great demo, and I am really excited for the full game!

OMG, Ren was horrifying and I loved it. The chase scene was excellent as was the horror in being caught, and its interesting how a certain three showed up after her death. The aesthetics of the horror bits and the contrast with the bright normal sections was just perfect.
