Well, I'd imagine you could modify the game with the Undertale Mod Tool, which works for most Gamemaker 2 exe files. So yeah, I bet people could easily modify the files since they're organized by name.
Tho uh, I'd prefer my game didn't become as popular as SCP! That's crazy popular, and I don't want something with that big of an impact -especially for a Vore game! ◑﹏◑;
But thank you for your kind words! Have a good day
