It's quite easy to multiply sprites many times, but when you need to make any changes .... Maybe you want to learn how to use clones, it's not too difficult. Look at the code of Sprite3 as a simple example. There's another glitch I recognized: The snowflakes tended to fall on the right side of the scene. This was because you placed them right of the center of the canvas. When you define a xy-position of a sprite it always refers to the center (+). Btw I like your project :)
