This is a site I ran across a while back. This guy makes some utterly amazing games with a very light-weight game editor called "Game Maker". If you are familiar with it, don't be fooled. This guy (Cactus) makes some of the most creative games I have ever seen. You must check out the game actually linked here, Psychosomnium, and then go to the main page to try out some others. Ad Naseaum 2 is another must-play, if just for the music. Simple, small downloads and no installation. Just unzip and play.

Let me know what you think. I think he has several that could have been at Pax10.
