It was fun to play and nice use of the color palette, liked the subtle differences when switching
Two things i noticed, first in your first level it says use arrow keys to move. so i expected up arrow was jump. It wasn't, luckily it was the standard spacebar to jump but it was a bit inconstant.
I see you use godot, in game jams i would always opt to make a web build as it takes a way the hurdle of downloading, waiting for windows and virus scanners to do their thing. Of course if you used the mono version forget what i said :D
