On Level Design

I was going to write a post about some aspects of Level Design, and the unwritten tutorial;
but was pleasantly surprised to find that a fellow had already written an excellent article on the subject.

Give it a read, it's pretty dang educational.

The most important thing to take away, design-wise, are the subtle tutorials that manifest themselves through gameplay. There is no handholding, there is no large text tutorial; those are symptoms of a designer who is not confident in his own design.
