Links on Level-Building

I'm on a computer game development course at the moment, studying the nuts and bolts of computer game production. I've set up an area of the site where I'll be placing playable work as I complete it.

I'm currently working on two projects; a maze-based game and a platformer. Each of these genres lives or dies by level design, especially the latter, so I've been doing some research on how to put together a decent platform game. Here are a couple of articles / posts that I found useful:

I've been referring to them all a lot, they cover the practical design process, the testing process and how you should look at escalation and complexity.
