I'm not a dating sim aficionado at all, but this demo did not disappoint! I've played through the game about 3 times now trying to see more scenes, and I found all the girls fun and interesting. The artstyle is also absolutely gorgeous, the animated portraits especially adding an incredible amount of charm and appeal to the dateable characters. My only complaints would be the use of the R slur in Yuyu's final scene, which I think would be best removed because of how carelessly it's used, and to a lesser extent, the inability to play as a girl. I understand that might require noticeably more work, but I do hope it's in the final game. All the characters are basically confirmed to be bi anyway!
