I removed the sun object for better performance and fixed other render priority issues of a few objects. I don’t know why I left the sun light in there in the first place.
I made one song in the background music less pitched again and painted 4 new paintings for the 3D objects in the game world that still had the basic polygon Grey before. I left some of the Objects with the old basic polygon Grey to respect the Art style decision I made before.
The game looks a small bit more colorful now.
