16x16 boss screen? 4.5.9

Is it possible for a 16x16 boss screen to work in the metrovania module?
I started making one thinking it would all be fine but I'm getting some strange things happening that don't happen normally with 8x8 screens, like enemy projectiles behaving differently and my enemy death animation not happening.
do the 16x16 screens HAVE to be for non main game state?
Sorry for the rookie question... been a while since I've worked on my game. (poor effort I know )
