Thank you very much for the update ^^
I checked out Demo 1.0 and even managed to translate a few lines by taking screenshots and using picture translator in order to get the meaning of certain scenes better (the "dream" scene, the "magic" scene, and a few lines in the finale). The plot is interesting and the characters seem to have a lot of secrets.
Main Menu UI looks so cool. I like it a lot. The game has nice colour scheme that fits the aesthetics of Taisho Era well.
P.S. There is a certain moment that may or may not be a bug: when Kotori is looking in the mirror (after the rehearsal with Kazuya right before meeting Hatsuyuki) Kotori isn't wearing a coat, but his mirror reflection does.
