I guess it's been a while, but I finally got around to making a small update for this.

• Added music and sound effects to all routes.
• Added widescreen (16:9) support, in addition to the existing 4:3 support.
• Updated to newest Ren'Py version, thereby improving performance and fixing several issues.
• Added backend support for modular new routes (in case I feel like releasing additional stories).
• Made the requirements for Ending 35 less strict.
• Fixed a few bugs.
• Minor text changes in a few places.
• Maybe other things I forgot.
