ALVY'S ROUTE IS SO GO0D BRUH. PLS MAKE IT A MAIN AND I CANT BELIEVE U LEFT US ON A CLIFFHANGER 😭😭😭😭😭😭
I think the last part of Scribbles route
(Being actually Scribbles) would be the "canon" story with Therium being key characters in the route (Hence his route being Scribbles's part 1) the other routes are basically just optional developments for the characters you like.
(Who knows, maybe chapter 2 you choose what ending you got before starting the game :D, although that's still a bit away)
