I enjoyed playing this game to the max! I could keep going on and on about all the things I loved in it and I won't be over. 😍
There are only some things I'd like to point out that you might want to take a look at:
1- The import save option in web: I was playing from Mac on web (Safari) and I had to exit the game and return back to it. I exported my save so that I can import it and continue where I left off, but the import didn't work. Even though a message that said "save successfully imported" popped up, the "Continue" button in main menu page didn't work so I had to skip from the buttons on the right.
2- The database error: In the middle of the game, an error message popped up frequently that it blocked some of the art/text of the game. I took a screenshot of it so you can analyze it here:

3- More choices: This one is a personal favorite since I'm one used to playing Choices & Episodes 😅 (Your game is way better than them by the way). And maybe in visual novels it's normal to have not so many choices in the demo since it's a just a demo.
There's one last thing you can do that'd help other developers (like me🤭) which is if you can add a hyperlink to the contributors of the game in the description's credits part. I'd like to check their profiles if they've ones on itch.io and if they don't I'd like to see the links you got your music and the rest of the assets from.
As a fan of this game, I'd also recommend you to post Dev Logs as I'm getting curious about the progress you made and how you brought this game to life. 😌
