Thanks for the comment! I had intended to respond before but, er, forgot. Sorry orz
You'll be happy to know that I do intend to do a commercial remake of this game once my current project is finished - actually, said current project is primarily a way to fund a Prom Dreams remake lol. It will of course have massive graphical updates, but I also plan to include some quality of life changes similar to some things you suggested (e.g. a fast travel instead of access to the elevator key) and some story expansion with regards to the three love interests. This will probably not happen for a while, but my game pages will all be updated with more information when I actually get the project off of the ground, so I hope you look forward to it!
