Hi, I'm creating a fire and ice level that functions similar to the core stage from Celeste, where the stage becomes cold or hot at the flip of a switch. I'm not the most ASM savvy person by any means, so I was wondering how I would be able to change an entire palette (or multiple palettes) of a level in the middle of playing said level. Perhaps with a lot of custom palette animations tied to a single custom trigger? Thanks for the help in advance.
For reference, this is the kind of effect I'm trying to recreate.
