Thank you very much for this awesome comment!! I'm so glad you enjoyed the game! I feel the same way about visual novels too, oftentimes, which is why I prefer to make more interactive games like this one that have visual novel elements (like plenty of dialogue, character portraits, etc). It was short because I originally made it for a game jam, but I plan to make some longer games in the future!
I'm sorry that it was so difficult to find that fullscreen option! I'm not sure if there's any way to pop it right in the menu with the game engine I used, but I'll look into it. That seems like something that should be possible. There was a file in the game's folder that contained control instructions as well, so I'll try to make that file more obvious!
The music wasn't actually created by me (they were all purchased or royalty-free tracks) so I'm not sure if I could legally distribute the game's soundtrack. I could send you a list of all the songs I used, though, if you'd like! That way maybe you could track them down yourself. :)
