I really liked the minimalistic art style! The first time I was playing it, I was stuck on the first art piece for awhile, it looked like the shape fits the ghost shape, but for some reason it wasn't registering. After I got through the first one the upcoming puzzles felt pretty easy. I also noticed some of the pieces would go back to the original size during the randomization phase, and I didn't have to touch them at all.
I really liked the minimal version of the last art piece, it's got complex shapes without feeling overwhelming. Congrats on your first Godot game!
