DNBML was created out of pure admiration of the previous games, DNBHERL and the original, DNBHL.
I loved the creative methods and was inspired by what 3nd3r5 and Lukasz created, and that led me to try to recreate those feelings!

You will need to search far and wide on the web, so don't be afraid of doing so.
Passwords will always be lowercase, no spaces, UNLESS you are told otherwise in the level!
The introductory levels are there to give you a synopsis of what you will be seeing later in the game, so keep methods you learn in mind.
Some levels won't hold your hand through it, so use what knowledge you have obtained from previous levels or try to stick to general rules of thumb when you're stuck.
