|Couldn't having that many layers cause memory usage issues? .-.
Yes, that's true. I don't know how to fix that, but you can also use the template to create levels and port them to existing slots later on. I recommend that, because I've heard a lot of people saying "Merp, Sky Station crashes whenever I make an edit" and all this stuff. Using this template, that shouldn't happen. Also, these template use the maximum ammount of layers.
