Game description:

2D lighting and shadowing engine for Game Maker 7 & 8.

Features real time lighting with smooth sprite-based shadows, volumetric lighting, sun shadows, ambient shadows, day/night cycle system, and some other stuff.

First released on the non-official french Game Maker community (LeCBNA.org) on June 3, 2010.
I've been meaning to publish it here once I had a proper english translation, but since it keeps popping up here under random names, it convinced me not to sit on my bottom any longer and publish it myself, even though most of the files are still in french.

You can find a video and a few other things on the original project thread:
