When you remix: - CHANGE SOMETHING! - keep the "coming soon" backdrop the last one. - don't change any previous levels, delete a level, delete a color, or change what a color does. - you can add a new color, but make sure you know what you're doing! - don't make a new level in between two existing levels (the "coming soon" screen doesn't count) - don't make an impossible level - don't add lives - don't add music, sound effects, or other stuff like that.
