Interesting way to have in this storytelling, creative use to make the player feel creepy while using bright tone asset.
I find the "Juicy" part of the story started late which make the game feel draggy. So either has more variety in gameplay to entertain the player till that part or have the "Juicy" part trigger often. Rotating make it hard to draw too.
overall, a fun way to tell a story by painting. I didn't expect GameMaker can be coded to be like MS paint.
