Thank you for the feedback! I can't change the controls as I built this using GB Studio, a game engine that you can use to make GameBoy games and export them as actual GameBoy roms or as HTML browser games. As the GB and the GBC only have a D-Pad, A and B buttons, and the Start and Select buttons, X and Z are the only keys I could map them to. I wanted to add something like the NPC suggestion you gave but I made this in the last 1.5 days of the jam (some stuff came up) so I couldn't add it. Thanks a lot for the feedback, I'll check out your project as well.
