Hi! Your game just popped up in my YouTube recommendations and the characters seemed familiar to me, like the characters from Salvamachine360. Are the route characters from a website where you can create them? Thanks for reading.
I made them at the time with a free sprite character creator, then edited certain aspects for certain scenes. It's been many years since I made this game and used the sprite maker. So I sadly don't remember where I found it but I did have to download it.
