Sensei, first and foremost, a huge thank you for playing this game. It's a pleasure to hear Hanae-san's voice in a horror game. Moreso, for a GoHome prequel. As for 20:09 - 20:13, this was easier to figure out for Japanese gamers and those who understand Nihongo. So, it's good to see that the game gave an additional clue for those in the west, with the 4-digit code flashing at the bottom of the screen.
This game's aesthetics are so good and Hana-chan's voice acting is as good as always, topping off with naturally having such a sweet voice what even was the point of the rhythm game at the end🤣
