How the passwords will work in my level sets/How many levels should I start off with when creating my first level pack?

I also suggest going with a smaller level pack to start. You get more feedback for your future levels. I'd start by releasing something you've made in a month or two, be it 10 or 100 levels or something in between. Then you can either add new levels in small doses to that set, or wait until you have a similar batch ready to release as a separate set. Don't feel the pressure to release every level you make, but rather have some self-censorship. Keeping in mind how someone else will feel when playing your levels will go a long way, and if you come up with some cool puzzles along the way, that is a big plus.

P.S. I like to choose passwords for pretty much every level I make. You can use numbers in yours if you want, and maybe some form of that could even be your calling card / signature to identify levels you make?
